Adhemerval Zanella 40c0a78068 Consolidate Linux semctl implementation 
This patch consolidates the semctl Linux implementation in only
one default file, sysdeps/unix/sysv/linux/semctl.c.  If tries to use
the direct syscall if it is supported, otherwise will use the old ipc
multiplex mechanism.

The patch also simplify header inclusion and reorganize internal
compat symbol to be built only if old ipc is defined.

Checked on x86_64, i686, powerpc64le, aarch64, and armhf.

	* sysdeps/unix/sysv/linux/alpha/Makefile (sysdeps_routines): Remove
	oldsemctl.
	* sysdeps/unix/sysv/linux/alpha/semctl.c: Remove file.
	* sysdeps/unix/sysv/linux/arm/semctl.c: Likewise.
	* sysdeps/unix/sysv/linux/microblaze/semctl.c: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/semctl.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/mips64/semctl.c: Use defaulf
	implementation.
	* sysdeps/unix/sysv/linux/semctl.c (__new_semctl): Use semctl
	syscall if it is defined.
	* sysdeps/unix/sysv/linux/generic/syscalls.list (semctl): Remove.
	* sysdeps/unix/sysv/linux/alpha/syscalls.list (semctl): Likewise.
	* sysdeps/unix/sysv/linux/hppa/syscalls.list (semctl): Likewise.
	* sysdeps/unix/sysv/linux/ia64/syscalls.list (semctl): Likewise.
	* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list (semctl):
	Likewise.
	* sysdeps/unix/sysv/linux/x86_64/syscalls.list (semctl): Likewise.

README 

This hierarchy supports Linux systems using the new
asm-generic/unistd.h, which removes many familiar old syscalls.  For
example, to implement open(), newer Linux architectures require glibc
to invoke the __NR_openat syscall with AT_FDCWD.  This hierarchy
provides all those implementations.

It also provides support for 32-bit platforms using the 64-bit kernel
syscall APIs, as the 32-bit ones are no longer provided.  Note that
newer ILP32 environments (x32 or AArch64:ILP32, for example) are
converting to use more 64-bit types in kernel syscalls, so that aspect
of this support is in more flux as of this writing.
