That stuff should go in directories like `gcc/config/PLATFORM/'.  Even better,
make the testsuite platform-independant.  And write the generators in
perl ;-).

What about a more generic mechanisim `--with-extratest=/path/to/test' 
that causes an extra testsuite in that path to be executed as part of `make
test'?  Maybe even the GCC testsuite could be based on an even more generic
harness mechanisim that expects test information in some agreed output
format (I'm thinking TAP) and tests everything and outputs it in a format
similar to the current format.
