I like the general idea here much better than [1] or the symlinks that
we have now. However I'm wary of the sed magic and the various ways it
might trip over. The resulting file has way more info than we need, but
then it also misses the multiline settings (which we luckily don't
need).

At the risk of duplicating stuff, I'd go with manually generated config
for shell with minimal amount of information. For now, we'd only need
this for HAVE_XAPIAN_COMPACT and HAVE_MAN (the latter of which could
also be dropped from Makefile.config).

BR,
Jani.
