[OE-core] [RFC][PATCH 00/14] mips64 support and sh4 support

[Khem Raj]

This patchset adds required bits into metadata for having
mips64/n64 support. I have tested the core-image-sato and core-image-minimal
builds and boots on qemumips64 and runs gcc regression testsuite.
It needs linux-yocto-dev kernel for now which can be obtained from
poky-extra repo. Additionally systemd-image on angstrom-next builds and boots
fine on qemumips64 as well.

Additionally it also adds bits to have SH4 root file systems to be
able to built and again core-image-sato builds for sh4 however qemu
machine support is not yet done but root file sytem boots fine on 
real hardware.

The images are tested on both eglibc and uclibc.

Any help in providing feedback or testing these patches is welcome.

I have tested them enough for over a month now.
