Well, one problem is that you have a package that advertises itself as
working on $ARCH (by having $ARCH in the package filename) but it may
not actually work on every CPU with that $ARCH so you can't safely
distribute it.

If you're going to go that route, why not just use -march=native?
Maybe also set $ARCH to "native" for lack of anything better to use,
and then it should be clear that you shouldn't redistribute the
resulting package.  I'm sure there's a way to work that into the 'if [
"$ARCH" = "i486" ] ...' stanza if you can find a way to add -fPIC and
set $LIBDIRSUFFIX appropriately on 64-bit machines.
