Android: Fix crash when compiling release mode for armv5

Browse Source 
When building in thumb mode for armv5 applications will crash
with SIGILL on startup. This has been observed on armv7 devices
and emulators. It could be a bug in the gcc 4.4.3 toolchain, but
since the other toolchains in the NDK have other bugs that
make it impossible to use them for building, we need to disable
thumb until the cross-compiler has been fixed.
