Does it work for you if you remove the HAVE_CPUID_H part[1] (plus
the respective #endif[2])?

The problem is still there in 7.3.0RC2.
The system does have cpuid.h, but this cpuid.h does not have __cpuid_count.
Here is a fresh build log from PHP 7.3.0RC2:

clang defines __GNUC__. clang identifies itself as gcc 4.2.1. If you want to check if it's
actually clang, you could check for __clang__.

I don't understand the compile failure under Clang, since the
respective code is guarded by defined(__GNUC__)[1].
Anyhow, we should use feature detection (AC_TRY_LINK) instead of
inferring by compiler, in my opinion.
