Android gcc 4.6 1107 optimization benchmark

[Chao Yang]

HI Michael,

The build log can be found at
http://people.linaro.org/~chaoyang/shared_sources/build_2011-08-19_20-33.log

The benchmark wiki page
https://wiki.linaro.org/ChaoYang/Sandbox/gccoptimization is updated on
1. Adding benchmark for -fno-inline-function option (the size is reduced a
bit)
2. Replacing O2 with O3 in  build/core/combo/select.mk (a bit better
results)

Thanks and regards
