Subject: [PATCH] configure.ac: fix __get_cpuid_count check to catch link
 failure

The test program will compile successfully even if __get_cpuid_count
is not declared.  The error for the missing symbol will only show up
at link time.  Thus, use AC_LINK_IFELSE instead of AC_COMPILE_IFELSE.

* configure.ac: (__get_cpuid_count check) use C_LINK_IFELSE instead
of AC_COMPILE_IFELSE.
