[git commit future 1/1] librt: provide missing prototypes for mq_timedreceive, mq_timedsend

[Khem Raj]

commit: http://git.uclibc.org/uClibc/commit/?id=8c8d9ffe9259661e11a06552c5ef7373b775660c
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/future

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.
