Ouch.  I'd be happy to process a ld PR for this, or I'll get to
it eventually.  Not that supporting a.out is of any particular
interest, but it shouldn't pollute the test-results.

You mean "when you run the test-suite with a target compiler,
the only other sim target with C test-cases doesn't need this". :)
I see bfin had a few C test-cases added the last year, nice.

I guess you missed fixing CRIS then. :)
I'm not overexcited about the crusade making "sim" a special
case, when it works using the same dejagnu spell as anything
else.  So _no_ adding compiler flags to the individual
test-cases for the globally needed options.

Linker flags, pointing to the right library, stuff like that...
See the baseboard file.  Different options for *-linux-gnu than
for *-elf though.  (Yes, the sim can run trivial cris*-linux-gnu
-static programs.)
