Incidentally, if that tag is meant to be connected to picking up
packages from the LCG/Genser areas, note that that platform tag format
was phased out with SLC4: the new LCG format is more easily
automatically computed from uname etc., and would be i686-slc5-gcc43-opt
for 32 bit, and x86_64-slc5-gcc43-opt for 64 bit.

Any bits in particular, Hendrik? This looks interesting, but as I don't
intend to build LFS (cross-compiled or otherwise) in the near future, a
pointer at any particularly enlightening bits about cross-compilation of
32/64 bit would be nice. (And might make my life easier re. 32 bit Rivet
builds for Genser!)
