The 2.6.0-2.8.0 upgrade seems to have lost the $ character but that was
a year ago.

I have some vague memory about autotools doing something nasty to @bar@
replacements containing shell variables like ${libdir} so this could
have been to work around that as otherwise you end up with libdir
hardcoded in to the file in an expanded form.

Assuming autotools does put something sensible into the file, it can
likely be dropped now.
