test: Define optional exception classes
According to musl libc author:
"C99 requires the FE_ macros to be defined if and only if the exception they
correspond to is supported"
So we define these macros to 0 if they are not supported. Support for these FPU
exceptions is not necessary for correct functionality, but makes some tests less
effective.
