Yes, but it remains “non-standard” to ld.so, ld, etc.

No, because we precisely want to check that Guile’s ‘dynamic-link’ finds
it, because that’s what is used in guix/utils.scm (in turn,
‘dynamic-link’ uses lt_dlopenext, which uses dlopen.)
Thus the influential environment variables are LTDL_LIBRARY_PATH and
LD_LIBRARY_PATH.
When we have a full-blown distro, all those *PATH variables will be
initialized by /etc/profile, so that everything is transparent. In the
meantime, one has to set them in their own ~/.bashrc.

I’d rather let users do one of the above than add something specific.
