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/x86_64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/mips/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. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Remove definition. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/recvfrom.c: Simplify includes.
