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.
