Depends exactly how it's broken. If it looks like a linker bug, the thing
to do is re-run the failing command line with "-v -Wl,-v -Wl,--verbose
--save-temps", and bundle up all the generated files along with a log of the
build. That way I can re-run (and debug) the failing link using just a
cross-binutils aimed at the target.
