Subject: [PATCH] Update x86 CPU detection configure check.
Commit 6577534a80c8 switched from using __get_cpuid() to
__get_cpuid_count(), but the corresponding configure check was not
updated.
Since __get_cpuid_count() was introduced much later, make sure we
check for the function we actually use.
Thanks to Mark Harris for the report.
