[Pixman] [PATCH] test: add a check for FE_DIVBYZERO

Some architectures, such as Microblaze, 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. Signed-off-by:
