posix: Consolidate Linux msync syscall
This patch consolidates the msync Linux syscall generation on sysdeps/unix/sysv/linux/msync.c. It basically removes it from architectures 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. * misc/Makefile (CFLAGS-msync.c): New rule. * nptl/Makefile (CFLAGS-msync.c): Likewise. * sysdeps/unix/syscalls.list: Remove msync from auto-generation list. * sysdeps/unix/sysv/linux/msync.c: New file.
