I set it to "" so that we'd build expat for the system we're building on...

Hi Bryan, thanks for the response--

Hmm.  Now I'm worried that I don't understand the problem I set out to
solve :)  I thought that "native gdb" meant "a gdb cross-compiled to
run on the target."  Whereas I thought that cross-gdb meant "a gdb
compiled to run on this host, targetted at a remote target."  So for
the first, we need a cross-compiled expat, and for the second we need
one which is compiled for the (for lack of a better term) "host"
system.  I'm confused as to why we could reuse the same build of
expat?  Maybe I've missed something major here.  Thanks again,
