Sure.  It shouldn't be too hard to implement because I can easily create
what I want by linking with the :::::: and then applying a second step
which replaces all those characters with '\0' bytes.  However, that
approach doesn't work for people whose ld tools check the RPATH
immediately.  We just need a flag that says how many extra zero bytes
should be allocated.

Are you volunteering, or asking me to do approach them?
