Folks,

it was reported that in Snow Leopard, Apple has removed support for
ppc64, and folks trying to use that receive fairly obscure errors.
Some of Boost users were already confused by this. Now, this is
of course more like Apple's problem, but here's a patch, against
current trunk, to do a nice diagnostic of this in Boost.Build.
The intention is that if you try to build just ppc64, or a two-way
fat binary including ppc64 you get an error message, and if you
try tobuild 4-way fat binary, ppc64 is skipped and you get 3-way
binary.

Can some of OSX users apply this patch to trunk and give it a try?
If it works, I would like to merge to release branch.

Thanks,
Volodya
