Fix __ASSUME_PSELECT for MicroBlaze (bug 16642).
Reviewing (for all architectures, with a baseline kernel version of 2.6.32) the kernel support for features for which __ASSUME_* macros would be affected by a move to 2.6.32 as minimum kernel version showed up that __ASSUME_PSELECT was wrongly defined for MicroBlaze, despite the corresponding syscall table entry not being wired up in the MicroBlaze kernel. This patch makes the MicroBlaze kernel-features.h undefine __ASSUME_PSELECT. I'd also encourage wiring it up in the kernel (so you can then make this #undef conditional, and eventually obsolete once a recent-enough kernel is required). I suspect it wasn't wired up because of the mistaken comment in asm/unistd.h "obsolete -> sys_pselect7" (there is no such syscall as pselect7). [BZ #16642] * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_PSELECT): Undefine.
