 Ok; this goes up to -march=armv6, but not -march=armv6t2; it also goes
 away in ARM mode.

 I filed LP #629671 to track this after reproducing with the latest
 native toolchain which has the latest Linaro released patches.

 One thing which would help is reduring the test case from -Os to a set
 of -f flags; you can find which flags are turned on by -Os with:
 arm-linux-gnueabi-gcc -c -Q -Os --help=optimizers
