linux-user: fix TARGET_NR_select
TARGET_NR_select can have three different implementations:
1- to always return -ENOSYS
microblaze, ppc, ppc64
-> TARGET_WANT_NI_OLD_SELECT
2- to take parameters from a structure pointed by arg1
(kernel sys_old_select)
i386, arm, m68k
-> TARGET_WANT_OLD_SYS_SELECT
3- to take parameters from arg[1-5]
(kernel sys_select)
x86_64, alpha, s390x,
cris, sparc, sparc64
Some (new) architectures don't define NR_select,
4- but only NR__newselect with sys_select:
mips, mips64, sh
5- don't define NR__newselect, and use pselect6 syscall:
aarch64, openrisc, tilegx, unicore32
