Description

Testingenabling ifunc support on FreeBSD, alongside having to remove the hardcoded check that disables it I also run into:

  checking for __builtin_cpu_init... no

AC_LINK_IFELSE([AC_LANG_PROGRAM([],[[    return __builtin_cpu_init()? 1 : 0;]])],[

While this does technically appear to returnint on gcc, it's documented asvoid __builtin_cpu_init (void), and indeed returns such on clang. Changing this to:

AC_LINK_IFELSE([AC_LANG_PROGRAM([],[[    __builtin_cpu_init(); return 1;]])],[

Results in a successful check and much faster addslashes, base64_encode, etc.
