For most packages you just need to set CFLAGS or similar to include -march

That's handy, thanks. Another interesting source of info
might be the rules in http://ptxdist.sf.net, which knows
how to cross-compile quite a few apps.
./configure --host=i486-pc-linux-gnu --target=i486-pc-linux-gnu
For complex packages which are prepared for Canadian Cross Compilation
(gcc/binutils/gdb/glibc etc), this can be right.
Heh. I'm doing that now, and it looks like I need to use
modified values for build and host (with _build and _host
appended to the manufacturer field) to force the configure
scripts into cross-compile mode. Not all i686-pc-linux-gnu's are
created equal!
