[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=0c449a7d1182a3c8cf8a0c0259d7dde737de1414
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Builds without thread support fail with the following error:

  ../src/pj/os_core_unix.c:45:21: fatal error: pthread.h: No such file or directory
   #include <pthread.h>
                       ^
  compilation terminated.
