--- Comment #69 from H. Peter Anvin <hpa at zytor.com> ---
I just pushed gas support for symbol subtraction (to generate SUBxx
relocations) into my binutils tree.

That is, one can now specify, say:

    mov (foo - "foo!"), %ax

... and get R_386_16 followed by R_386_SUB16 (or R_386_32 followed by
R_386_SUB32 if applicable.)

It should work anywhere there is a symbol, pretty much.
