[oe] [PATCH][v4] Make multi-machine toolchains to co-exist (revised again)

[Tom Rini]

Hey all,

As one of the folks who suggested something else, here's my take.

We modify the prefix for cross stuff to dump everything into
MULTIMACH_TARGET_SYS in the sysroot.

Pro: It should work for all the cases
Con: We're back to having a 'special' directory of cross stuff
Pro: It's separate but still valid for $ORIGIN mangling, which is the
other problem we had before.

I've got a qemuarm console-image and then beagleboard console-image 
build going now and that's going to take time.
