[testsuite PATCH] Fix -m32 gcc.target/i386/pr102464-vrndscaleph.c on RedHat.

[Roger Sayle]

This patch fixes the 4 FAILs of gcc.target/i386/pr192464-vrndscaleph.c
with --target_board='unix{-m32}' on RedHat 7.x.  The issue is that this
AVX512 test includes the system math.h, and on older systems this provides
inline versions of floor, ceil and rint (for the 387).  The work around
is to define __NO_MATH_INLINES before #include <math.h> (or alternatively
use __builtin_floor, __builtin_ceil, etc.).

This patch has been tested on x86_64-pc-linux-gnu with make -k check,
with and without --target_board=unix{-m32}.  Ok for mainline?

        * gcc.target/i386/pr102464-vrndscaleph.c: Define __NO_MATH_INLINES

Thanks in advance,
