The optflags macro is read on a per-platform basis. Rather than trying 
to have a single ~/.rpmrc that works on all your platforms, you might 
consider installing a platform-specific /etc/rpm/macros on each build 
host. On you sparc, for instance, your /etc/rpm/macros could be

%optflags  -O3 -mcpu=v9

(Of course, if your host isn't running an Ultra, you'll want to change 
v9 to v8 or something more appropriate.)

I'm not sure that helps. Does it?
