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 Reported-by: Timothy Pearson <tpearson@raptorengineering.com> Reported-by: Allan Wirth <awirth@akamai.com> Suggested-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
