+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.

+[Thomas: switch to an autoconf check.]
