Subject: Consolidate Linux fcntl implementation

This patch consolidates the fcntl Linux syscall generation on
sysdeps/unix/sysv/linux/fcntl.c.  It basically removes all the
architecture specific implementations.

Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.

	* sysdeps/unix/sysv/linux/arm/fcntl.c: Remove file.
	* sysdeps/unix/sysv/linux/generic/wordsize-32/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/hppa/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/m68k/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/microblaze/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/mips32/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/mips64/n32/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/s390/s390-32/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/sh/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc32/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/fcntl.c: New file.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/fcntl.c: Refactor to
	use default implementation.
