First of all can you explain what compiler issue there is? Both
{arm,aarch64}_print_operand() handle 'c' (but of course I can't
tell whether correctly).

And then can't you possibly find ways to deal with the # prefix
added when not using 'c'? For the section name (if you need the
section split in the first place) I would think a # should be fine,
and the uses in expressions can surely be worked around by
interposing an assembler macro (even if that macro may end up
looking quite ugly).
