Whoops, my original concern was a total red herring. My description of
-nostdlib is valid for GNU ld, but not for the ld we actually use, about
whose lineage I am unworthy to hypothesize. Sorry for the confusion.
In our current ld, all -nostdlib does is prevent -L/usr/lib from implicitly
appearing in the linker's environment. Searching of -lgcc -lc or crt0.o is
not affected by it. (grep for std_search_path underneath gnu/usr.bin/ld)
Given this, I'd say your use of -nostdlib is not gross at all, but totally
appropriate -- it's about the only thing our -nostdlib would be good for.
However if we ever migrate to GNU ld, this might become a migration issue.

Okay. This certainly helps explain why libgroff hated my guts for switching
back and forth between gcc/egcs a few times in one week.
