Hm - when compiling, or on the target?
Until now, my projects worked just fine with just libgcc.a, however my
experience is limited to m68k and PPC. Did I miss some case where I would
really need libiberty?

Ah, great - that *definitely* belongs in the FAQ, IMHO.

That's what I did (and edit the toplevel Makefile, IIRC). However, it would
be nice if I could simply tell configure that I want to build a 'small'
compiler without the optional stuff - that would make it a lot easier do
automatically build new compiler versions.
