Fix the C89 compilation of some tests

Two tests assumed they were built to the C99 standard when in fact only
the star-3d library needs to be built in C99 (because of Embree). Its
API remains purely C89. In this commit we update the offending tests to
be C89 compliant by explicitly enabling the POSIX 2001 standard required
by the expf, nextafterf, and fabsf functions they use.
