Because of the lack of racial weapons in the SRD, I just came up with my own.
I freely admit that I stole some ideas - mainly from the Lord of the Rings movies.
First, the table - Sorry for the formatting, but if you paste it into your favourite spreadsheet, it should work out.

f. You can use weapon finesse with this weapon
r. This weapon has reach
*. See Special rules below
An-gresch, orc: Although you can use this weaponin one hand, using it in two hands will lend extra lethality to your attacks, increasing the crit multiplier
Feyspear, gnome: This weapon has reach, but you can still attack adjacent targets.
Flailsling, halfling: Though this is a ranged weapon, you can make melee attacks with it without penalty.
Strongbow, composite elven: Like other composite bows, composite elven strongbows are made with a specific strength score in mind. The standard composite elven strongbow is supports a +0 Strength score. Every point over 0 costs an additional 150 gp. As usual, the composite elven strongbow is treated as an elven strongbow for the purpose of feats like weapon focus.
Just to add, all those weapons are applicable for weapon familiarity by the respective races. The whole exercise is to create such weapons.
I won't bother with the legal stuff, but as far as I'm concerned, they're open content, blablabla.
About the weapons, sorted by Race:
Halflings
Halflings favour weapons they can use with agility rather than brute strength, and also value versatility. Why use a weapon that can fill one role if you can have one that fills two?
Longknife: The halfling longknife is a variation on the dagger. It features a long but slim blade, perfectly balanced for both hand-to-hand combat and throwing.
Flailsling: Halflings like slings, but the fact that if you use one, you leave yourself open to melee attacks never set well with them. Their solution is the halfling flailsling. The cradle is strengthened to serve as a bludgeon.
Gnomes
Gnomes found a way to off-set their short stature, actually get the reach advantage on many foes, and turn the whole thing into a spectacle, too.
Feyspear:The feyspear is a bit longer than a normal spear, but not as long as a longspear, just long enough to gain reach with a bit of special training. You can still use it to attack adjacent targets.
Traditional feyspears are made from a single piece of wood, including the spearhead, which is formed and hardened by gnome druids using fey magic. They're never quite straight and look quite natural (other races sometimes adapt the weapon, but usually follow more mundane techniques to create the weapons).
Gnomes typically adorn the spearhead with brightly-coloured ribbons, which results in them being seen long before you see the gnome itself (the spears are longer than the gnomes are tall). This is intentional, as gnomes usually want to proclaim their arrival.
When the ribbons come off, though, it's hard to spot them in the forest at all, and a gnome you can't spot can be quite dangerous. There's a gnomish saying based on it: "The ribbons have come off", meaning that fun and games are over and things are getting dead serious.
Dwarves
Dwarves are pragmatic. They want weapons that are tools, too, so they neither carry something around all day they only need in emergencies, but won't be helpless in emergencies because they wanted to loose the extra baggage.
Greathammer: Used to turn rocks into rubble, break through obstacles, and turn enemies into pulp. The dwarven greathammer features a long handle, a massive head on one side, and a small counter-weight on the other. The hammer is held in the middle to let the counterweigt do its work. If used right, the momentum is enormous, and the weapon can deal devastating blows.
Orcs
Orcs have no use for practicality, or grace, or anything like that, especially not in their weapons. What they care for is sheer brutality and ability to kill.
An-gresh: These swords are crudely made, but somehow, they're still effective. Orcs with their great strength can easily use them in a single hand, but when used with two hands, the weapon becomes more dangerous.
(Think Uruk-hai-made swords here)
Elves
Swordsmanship and archery are part of elven nature, and their weaponmaking efforts are tightly focussed on bows and swords. They value effeciency but never neglect grace. Elven swords are usually used with agility rather than brute force.
Skirmish Blade: A relatively short, slender, curved blade. Often carried as a fallback by those who use larger weapons or specialises in archery. Those who use it as their weapon of choice usually use them in pairs (often called blade dancers)
Battleblade: Basically a longer version of the skirmish blade, used as a primary weapon. Though usually used in one hand (either alone or with a skirmish blade in the off-hand - such fighters are called battle dancer), the handle is long enough for the weapon to be used two-handed in a pinch.
Warblade: A two-handed weapon with a very long grip, and long, slender blade, used mainly in heavy fighting situations, usually in formation. As with all elven blades, it can be used with grace rather than brute force.
(Think Lord of the Rings High Elven Warrior Sword from the openening fight)
Strongbow:
Though not much larger than a longbow, the strongbow's construction lets you pack a bigger punch, mainly because of the form and materials used.
