I am not sure if you understand this or not, but you need to have a series
of toolchains for each arch you need to cross compile at different
locations.
For different binaries of different arch, I would suggest you use different
directories of same source code. Generally make clean or distclean should
get rid of most binaries, but starting a clean build is always the best
idea.
Toolchains can be bit of a pain to get right.
