| Fix missing PTHREAD_MUTEX_RECURSIVE_NP |
| |
| The musl C library does not provide the non portable |
| PTHREAD_MUTEX_RECURSIVE_NP. In addition, uClibc does not define it as |
| a #define, but as an enum value, so doing a #if defined() check |
| doesn't work properly. Instead, add a AC_CHECK_DECL() autoconf check. |
