I'm confused about which directory you are using (is it /mnt/disk/tmp or
/tmp?). You might need to use the -f option to ldconfig if you are running it
during preparation of the rescue disk.
The LD_LIBRARY_PATH variable should work, unless bacula-fd is installed with
the setuid or setgid bits set. You could try adding ldd to the rescue disk
and see what it reports at rescue time, with LD_LIBRARY_PATH set.

It was possible in the past by adding --enable-static-fd to the configure
args, but I don't know if that still works.

Yes, that is a workable solution too. I would keep the package file
(i.e. build it with make package) to avoid needing to install any development
tools at recovery time.
