OK, thanks. So I ended up with the below as a probably-2.6.23 thing:
From: Roland McGrath <[email protected]>
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.
