[google] Backport r177357 from trunk to google/gcc-4_6 (issue4862042)

[Guozhi Wei]

Hi

The trunk patch r177357 fixed an arm target test failure, which also affects
google/gcc-4_6, OK to port it to google/gcc-4_6?

Tested with
make check-gcc RUNTESTFLAGS="--target_board=arm-sim/arch=armv7-a 
arm.exp=vfp-1.c"

thanks
