The question is how portable you want to be.  Only Gentoo?  Only
GNU/Linux?  Only ELF systems?  Only GNU binutils ld?  Or also, say, w32,
or AIX non-runtimelinking, or otherwise native non-GNU linker?
Can we assume the libGL and libX11 all come from
Is using a wrapper shell script acceptable for you?
Is patching a binary (a la objcopy) acceptable for you?

Because it's inherently not very portable.
