pull build configs into Git.

Fathi,

Since we're at the start of 12.05 we need to shift the builds over to the tip toolchain and stop daily builds for various baselines. I figure we can also get the configs into git. Do you want to take care of getting the current configs into git and then shift the builds or the other way around?

For 12.05 I'd kill all dailies except for the tips listed on android-build.linaro.org under:

"Users who are interested in tip builds with Linaro goodness should use:"

People can always re-enable dalies they're interested in.
