test: add a check for FE_DIVBYZERO
Some architectures, such as Microblaze and Nios2, currently do not
implement FE_DIVBYZERO, even though they have <fenv.h> and
feenableexcept(). This commit adds a configure.ac check to verify
whether FE_DIVBYZERO is defined or not, and if not, disables the
problematic code in test/utils.c.
