This breaks the build in at least Alpine Linux 3.4, 3.5 and 3.6 and
android-ndk:r15c-arm

Probably others, I'll investigate later, feel free to do it if you have
the time now :-)


Sorry about that. That's probably because FNM_EXTMATCH is a GNU extension, not POSIX, and the Alpine and Android runtimes likely don't implement that... I'll send a fix reverting back to the strncmp to ignore the uncore_ prefix,
and dropping that extension.
