Revert change I7af83e21c64d217c6b28bf6cb5ee2e2f23182c95 to fix Froyo build.

Apparently, that change that supposedly fixed AT-related ARMv7 bug broke
DexOpt step in the build process, resulting in trashed files that crash
the device. Rolling this change back to fix Froyo, until cause of the
DexOpt breaking has been found and fixed
