    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.
