Might you be looking for this one?

`--relax'
`--no-relax'
     An option with machine dependent effects.  This option is only
     supported on a few targets.  *Note `ld' and the H8/300: H8/300.
     *Note `ld' and the Intel 960 family: i960.  *Note `ld' and Xtensa
     Processors: Xtensa.  *Note `ld' and the 68HC11 and 68HC12:
     M68HC11/68HC12.  *Note `ld' and PowerPC 32-bit ELF Support:
     PowerPC ELF32.
     [...]

That's a linker option. GNU ld seems to accept it on every target, but
usually it doesn't do anything.

GCC 4.1 for example does have -mrelax on at least some targets on which
--relax does something, but not everywhere, so the portable version
would seem to be -Wl,--relax.

I can't find a -r option for GCC, but GNU ld has

`-r'
`--relocatable'
     Generate relocatable output--i.e., generate an output file that
     can in turn serve as input to `ld'.  [...]

Again, use -Wl,-r.

Hope this helps.
