another cross-gcc question ("can't compute suffix of object files")

[Steve Franks]

Sorry to be such a pest,  I'm trying to go from being a good hardware
programmer to a good OS programmer, but there's alot to pick up to be
FreeBSD proficient...

Can't seem to do a vanilla cross-gcc on my home system, which works
fine on my work machine, both of them are recent 7.2 installs...

I don't even know what other info would be needed to track this down.
My machine is pretty much useless without an arm compiler - that's
what I do for work.

Best,
Steve
