<sigh> I was able to work around this for i386, but apparently for
Alpha (and PowerPC also, I think; maybe more) the bug was somewhat more
complicated.

Set c-compiler and c++-compiler in a board description file (and any
others you care about).  You can do this by:
  Copying dejagnu/baseboards/unix.exp to a new name in the same
directory
  Edit the copy
  Run the testsuite as '$path/runtest --target_board your-board' or
with RUNTESTFLAGS="--target_board your-board" if you use make check.

Note that you've got to run the copy of DejaGNU in the source
distribution for that to work... or install the baseboard in the global
dejagnu config directory off under /usr/share somewhere.
