I don't think the burden would be toooo high, although it will mess the
code up a bit.

The post-build checking for section reference mismatches will help,
although that seems to have got itself turned off (what happened
there?).

Did anyone look at writing a postprocessor for the .s files?  It
doesn't look like it will be too hard from an initial peek.

Did anyone ask the gcc developers?  I'd have thought that a function-wide

	__attribute__((__string_section__(foo))

wouldn't be a ton of work to implement.
