OK, thanks. So I ended up with the below as a probably-2.6.23 thing:
From: Roland McGrath <roland@redhat.com>
The assembler for a while now supports -gdwarf to generate source line info just like the C compiler does. Source-level assembly debugging sounds like an oxymoron, but it is handy to be able to see the right source file and read its comments rather than just the disassembly. This patch enables -gdwarf for assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.

If there are problems it'll most likely be with oddball architectures running older compilers, I guess. If something blows up we might need to make this an arch/foo/Makefile thing.
