commit: http://git.uclibc.org/uClibc/commit/?id=cfe1298282b9b49f11c0002b1f9cc98da2ad0065
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master
If ADVANCED_REALTIME is disabled, these prototypes are missing and
librt_hidden_proto() fails.
Makefile.in: added a comment, we build mq_timedreceive/mq_timedsend
on NPTL even if ADVANCED_REALTIME is disabled.
