Hey,

Previously, this test was added to fix this bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112337. However, it did not check the compilation options before using them, leading to errors.

This patch fixes the test by first checking whether it can use the options before using them.

Tested for arm-none-eabi and found no regressions. The output of check-gcc with RUNTESTFLAGS="arm.exp=*" changed like this:

Before:
# of expected passes          5963
# of unexpected failures      64

After:
# of expected passes          5964
# of unexpected failures      63

Ok for master?

Regards,
Saurabh

        * gcc.target/arm/pr112337.c: Check whether we can use the compilation options before using them.
