[PATCH, GCC/ARM, 1/10] Fix -mcmse check in libgcc
This patch is part of a patch series to add support for Armv8.1-M
Mainline Security Extensions architecture.
Code to detect whether cmse.c can be buit with -mcmse checks the output
of host GCC when invoked with -mcmse. However, an error from the
compiler does not prevent some minimal output so this always holds true.

* config/arm/t-arm: Check return value of gcc rather than lack of
output.
