Workaround for a gcc-4.6 bug on -fstrict-volatile-bitfields.

-fstrict-volatile-bitfields is set on by default on gcc-4.6
for ARM target. This causes an inline asm() error. While
upstream gcc community is working on the patch, we shut
off this option temporarily.

This patch does not affect gcc-4.4.3 build.
