That was also my conclusion, after examining the xxx.s xxx.d xxx.r files
in ld and gas testsuites. The fact that the .d files are disassemblies
means that consistent objdump behaviour is a prerequisite, but that
shouldn't be a problem. (Directly using the output of avr-as
-ahl=/tmp/test.l wouldn't check the object file. I think we need to use
objdump, as appears to be done in the existing testsuites.)

Dmitry has made a start, but we are considering moving to compatible .d
format before making too many test cases.

Anyway, no simulator needed, when we're only checking the assembler.
