Hi
Following series of 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
${TARGET_ARCH}-${CPU_SUB_TARGET}_${VENDOR}-OS
which means that a toolchain for armv7 is called armi-v7a_oe-linux-gnueabi-*
and for armv5te its called arm-v5te_oe-linux-gnueabi-*
They can coexist in same native sysroot. The symlinks would mean that
gcc will not accidently mix the assemblers or linkers.
MULTIMACH-* is not needed anymore as the TARGET_SYS is distinct enough
to serve same purpose.
I have booted a minimal-image on qemuarm qemuppc successfully. The build for
beagleboard in same sysroot went fine too. So I am confident of
these patches.
Please give it a shot in your environments
If these patches look ok we can commit them and bump ABI once again
Thanks
