After a resent GCC change the previously submitted BMI/BMI2 intrinsic
test started to fail with the following warning/error.
ppc_cpu_supports_hw_available122373.c: In function 'main':
ppc_cpu_supports_hw_available122373.c:9:10: warning:
__builtin_cpu_supports need
s GLIBC (2.23 and newer) that exports hardware capability bits
The does not occur on systems with the newer (2.23) GLIBC but is common
on older (stable) distos.
As this is coming from the bmi-check.h and bmi2-check.h includes (and
not the tests directly) it seems simpler to simply skip the test unless
__BUILTIN_CPU_SUPPORTS__ is defined.
