Thanks!

Nope, that doesn't work.  I think things would become much clearer if
you read the code in cross/lib/Makefile.in; I'm bad at explaining
things.

We're talking about a half in-tree, half out-of-tree build: the cross
compiled part is built ``out-of-tree'', while the libgnu.a used on the
build machine can either be built in-tree or out-of-tree.
