build: 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.
(__get_cpuid check): Likewise.
