move pthread_setaffinity_np check to the build system
Rather than trying to encode all of the rules in a header, lets just put them in the build system where they belong. This fixes the build on FreeBSD, which does have pthraed_setaffinity_np, but it's in a pthread_np.h, not behind _GNU_SOURCE. FreeBSD also implements cpu_set slightly differently, so additional changes would be required to get it working right there anyway. v2: - fix #define in autotools Fixes: 9f1bbbdbbd77d346c74c7abbb31f399151a85713 ("util: try to fix the Android and MacOS build") Cc: Emil Velikov <[email protected]> Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Eric Engestrom <[email protected]>
