You would need to use ld-wrapper, not ld, so that ld-wrapper sets the
RUNPATH appropriately.
But this won’t fix the problem above. The problem above is that glibc
is not in the search path. To fix that, a simple fix would be to add a
wrapper atop ld-wrapper (!) that would add “-L /gnu/store/…-glibc/lib”.
Perhaps there are more elegant ways to achieve it though. How is ld
invoked? Would it work to add that -L flag directly in the code that
invokes ld?
HTH!
