Consolidate Linux connect implementation
This patch consolidates the connect Linux syscall implementation on sysdeps/unix/sysv/linux/accept.c. The changes are: 1. Remove connect from auto-generation syscalls.list on the architecture that uses __NR_connect. 2. Define __NR_connect as default (__ASSUME_CONNECT_SYSCALL) and undef for architectures that do not support it. 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 connect from auto-generation list. * sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/generic/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/hppa/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/mips/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/connect.c: Simplify include list. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_CONNECT_SYSCALL): Define. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_CONNECT_SYSCALL): Undef if kernel does not support it. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_CONNECT_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_CONNECT_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h (__ASSUME_CONNECT_SYSCALL): Likewise.
