[Mesa-dev] [PATCH v2] c11/threads: Use PTHREAD_MUTEX_RECURSIVE by default

[Felix Janda]

Previously PTHREAD_MUTEX_RECURSIVE_NP had been used on linux for
compatibility with old glibc. Since mesa defines __GNU_SOURCE__
on linux PTHREAD_MUTEX_RECURSIVE is also available since at least
1998. So we can unconditionally use the portable version
PTHREAD_MUTEX_RECURSIVE.
---
Previous patch didn't work as intended since on glibc these are
part of an enum and not defines.
