Description

Testing enabling 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 return int on gcc, it's documented as void __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.
