VxWorks' libc doesn't define __STDC_LIMIT_MACROS when compiling C++98,
and then GCC's stdint.h doesn't define INT<N>_MIN, that a number of
acle asm testcases expect. If the macro is not defined, define the
macro in the header first included by all the affected tests, namely,
{div_s{32,64},mul_s{16,32,64,8}}.c.
Regstrapped on x86_64-linux-gnu. Also tested with ppc-vx7r2,
ppc64-vx7r2, arm-vx7r2, and aarch64-vx7r2. Ok to install?
for gcc/testsuite/ChangeLog
* gcc.target/aarch64/sve/acle/asm/test_sve_acle.h
(__STDC_LIMIT_MACROS): Define.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
