Backport from trunk r187586
http://gcc.gnu.org/ml/gcc-cvs/2012-05/msg00583.html
Enable -fstack-protector support for Android targets.
The patch only affects targets where __BIONIC__ is defined.
Built Android arm toolchain.
Would like to commit the patch to google/gcc-4_6 and
google/gcc-4_6_2-mobile.
OK?
