You should also have got test results from the generic parts of
the test-suites, and output in obj-avr/gas/testsuite/gas.log.

Ignore site.exp, it's just there to confuse you.  No magic. Copy
the .exp:s I quoted and just s/mmix/avr/.  All framework set, no
need to copy anything else; go write the actual tests.

Heh, actually looking at the source would help...  or not.
It's in gas/testsuite/lib/gas-defs.exp.  (Actually copied all
over; it's in other generic testsuites as well, just like
run_dump_test.)

You probably want to improve the ld testsuite for avr as well.
Mostly the same thing, just in the ld directory.
