This patch consolidates the select Linux syscall implementation on sysdeps/unix/sysv/linux/select.c. The changes are: 1. Remove select from auto-generation syscalls.list on the architecture that uses __NR_select. 2. Remove generic implementation add a default one that handle all current cases (with the expection of alpha) The new default implementation will either use __NR_select if available of fallback to __NR_pselect6 otherwise. 3. Add a alpha outlier implementation which requires old compatibility symbols. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_routines): Add osf_select. * sysdeps/unix/sysv/linux/alpha/select.c: New file. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove select and osf_select from auto-generation list. * sysdeps/unix/sysv/linux/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/generic/select.c: Remove file. * sysdeps/unix/sysv/linux/select.c: New file.
