[PATCH 6/6] uclibc: Fix bug exposed by udev 168+ for mips architecture

[Khem Raj <raj.khem@gmail.com>]

newer udev uses sgnalfd + epoll and this exposed a bug
in uclibc for mips where SFD_NONBLOCK should be defined
with 0200 for mips but was using 04000. This would cause
random segfaults in udev during boot process

Tested on qemumips/angstrom console-image since angstrom
uses udev 171. It worked well when we did not use meta-oe
layer because udev in oe-core will then be used which is
at version 164.
