When /proc is not mounted, a relative RPATH causes to fall
back to using the working directory as the base directory for RPATH
resolution instead of using the (unknown) location of the executed
binary. This issue is hard to diagnose, because the error message does
not make it clear that fallback code is in use due to readlink
/proc/self/exe failing. Furthermore, it may pose a security risk by
loading libraries from unintended locations.

Let's codify that in the bts.

Steps to reproduce (for glibc maintainers):

Create an unstable chroot. Install ghc. Do not mount /proc in that
chroot. Execute /usr/bin/ghc. You shall see that it fails loading

I assume that any binary with a relative RPATH is affected.
