legacy-support: unable to build on Leopard PPC

[kencu (Ken)]

Please do not update legacy-support to this commit until this is resolved, as it looks like there

This is building the software directly from the checkout of the git repo.

At present, I am not sure exactly what to do to fix this issue.

The makefile now hard-codes in -arch flags, and these may not be supported by all the compilers we expect to use (we may have to hack out some compilers then, the ones that don't support (multiple?) arch flags).

I assume that something is calling in the same arch multiple times to generate this error. I am a bit out of my depth in this level of Makefile... maybe we have to somehow hack in a "FORCE_ARCH" setting?

At any rate, at present
