[12/13] posix: Consolidate Linux mq_timedreceive syscall
Commit Message
This patch consolidates the mq_timedreceive Linux syscall generation
on sysdeps/unix/sysv/linux/mq_timedreceive.c. It basically removes it
from architecture auto-generation list.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu,
sparc64-linux-gnu, and sparcv9-linux-gnu.
* rt/Makefile (CFLAGS-mq_timedreceive.c): New flag.
* sysdeps/unix/sysv/linux/mq_timedreceive.c: New file.
* sysdeps/unix/sysv/linux/syscalls.list (mq_timedreceive): Remove
from auto-generation list.
