[wplug] Building redhat from source

[bgtrio at yahoo.com]

Well, rpmbuild has a --target option that seems to allow you to specify a 
target cpu, so 

rpmbuild --rebuild --target=athlon *.srpm

ought to override the spec for the cpu target.  I haven't tried this yet, 
but that's my understanding of how this could be made to work.

As far as terabytes of disk space, of course you wouldn't try to do them 
all at once, you'd do them in sequence.

Am I missing something?
