The default ";#" is reasonable.  It seems most port-overrides
are unnecessary.  Usually, for gas derivates, either ";" is a
comment character and the "#" is ignored with the rest, or ";"
breaks a new line and in most of those cases, "#" acts as a
(line-)comment character.

Do you actually need this?  What happens if you don't?
Does ';' do anything else in the netbsd-elf assembler?  Isn't it
a gas derivate?

I think this might be related to properly emitting #APP and
#NO_APP from gcc to gas.
