[oe] [PATCH 0/3] Make multi-machine toolchains to co-exist.

[Khem Raj]

Hi

Following three patches are for making multi-machine toolchains co-exist with
new cross staging for toolchain.

It changes the toolchain triplet from TARGET_ARCH-VENDOR-OS to TARGET_SUB_ARCH-VENDOR-OS

which means that a toolchain for armv7 is called armv7-oe-linux-gnueabi-*
and for armv5te its called armv5te-oe-linux-gnueabi-*

They can coexist in same native sysroot. The symlinks would mean that
gcc will not accidently mix the assemblers or linkers.

I have booted a minimal-image on qemuarm successfully. The build for 
beagleboard in same sysroot is underway.

Please give it a shot in your environments (especially Koen's env)

Thanks
