use a single libc and deduplicate threading code

Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.

- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
  -lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance
