Consolidate Linux send implementation

This patch consolidates the send Linux syscall implementation on sysdeps/unix/sysv/linux/send{to}.c. The changes are: 1. Remove send from auto-generation syscalls.list on the architecture that uses __NR_send. 2. Define __NR_send for architectures that supports it. It was done instead of defining in default kernel-features.h because current Linux practice for new ports are to implement only __NR_sendto [1] and it will require adding new kernel-features for ports that do not require it (aarch64 for instance). 3. Remove __ASSUME_SENDTO_FOR_SEND_SYSCALL and decide to use __NR_sendto for send generation based on __ASSUME_SENDTO_SYSCALL. 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/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Define. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Undefine. * sysdeps/unix/sysv/linux/nios2/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Likewise. * sysdeps/unix/sysv/linux/tile/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Likewise. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_RECV_SYSCALL): Define. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Remove define. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove send from auto-generation list. * sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewike. * sysdeps/unix/sysv/linux/mips/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/send.c: Simplify includes.
