  The code dealing with variants is purely a GCC specific feature that
I don't know a whole lot about, as I didn't write it, (Doug Evans did)
and as a result there is zero docs I know of on this feature. Testing
variants is buried in the multilib support. If you just want to
change this to "--endian-little" you could do this in the base board file
for your target, or change $CFLAGS.

  I daydream of rewriting the mulitlib test code by moving out of DejaGnu
proper, and into gcc/testsuite... and then cleaning it up so it's more
clear how to use it.
