Consolidate Linux recvfrom implementation
This patch consolidates the recvfrom Linux syscall implementation on
sysdeps/unix/sysv/linux/recvfrom.c.  The changes are:

  1. Define __ASSUME_RECVFROM_SYSCALL by default
  2. Undef it for  architectures that do not support __NR_recvfrom.

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/alpha/syscalls.list: Remove recvfrom from
	auto-generation list.
	* sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/generic/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/hppa/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise.

	* sysdeps/unix/sysv/linux/i386/kernel-features.h
	* sysdeps/unix/sysv/linux/kernel-features.h
	(__ASSUME_RECVFROM_SYSCALL): Define by default.
	(__ASSUME_RECVFROM_SYSCALL): Undef it if kernel does not support
	__NR_recvfrom.
	* sysdeps/unix/sysv/linux/m68k/kernel-features.h
	(__ASSUME_RECVFROM_SYSCALL): Likewise.

	(__ASSUME_RECVFROM_SYSCALL): Likewise.

	(__ASSUME_RECVFROM_SYSCALL): Remove definition.

	(__ASSUME_RECVFROM_SYSCALL): Likewise.
