#60147: legacy-support: unable to build on Leopard PPC

--------------------+----------------------------
 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
