Created a patch file for the MIPS specific signalfd mode properties. Mips
has different values for the signalfd properties.
See: http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=c66a1d17f9a7a1170e95e7cff5856ee6c6f695c2
Make the udev application work. Signalfd functionalit was not working, mips
architecture requires a different bit mask. Patch file attached. udev also
requires additional user groups. User groups added.
