libstdc++: testsuite: require cmath for exp simd
simd_math.h assumes declarations for many C99 functions to be present,
that libstdc++ doesn't add to target systems that don't have them in
the C library.
Add the C99 math requirement to tests for simd features, so that they
don't fail because of limitations of the target C library.
for libstdc++-v3/ChangeLog
* testsuite/experimental/simd/standard_abi_usable.cc: Require
cmath support.
* testsuite/experimental/simd/standard_abi_usable_2.cc:
Likewise.
