Are there simulators for these targets?  When running make check for
each of these targets, there are UNTESTED testcases, presumably because
they need a simulator:

WARNING: Assuming target board is the local machine (which is probably
wrong).
You may need to set your DEJAGNU environment variable.

binutils:
UNTESTED: strip
UNTESTED: strip with saving a symbol
UNTESTED: simple objcopy of executable
UNTESTED: run objcopy of executable
UNTESTED: run stripped executable
UNTESTED: run stripped executable with saving a symbol
ld:
UNTESTED: NOCROSSREFS 1
UNTESTED: NOCROSSREFS 2
UNTESTED: S-records
UNTESTED: S-records with constructors
UNTESTED: undefined
UNTESTED: undefined function
UNTESTED: undefined line

I don't know anything about cross-testing with dejagnu, though, so maybe
I'm doing something wrong.
