You're right, we probably need an explicit --enable for now.  Putting
that around the pcre checks and setting a flag to test in the .mdd
file should be good enough.

That then creates a dependency of the zsh package on the pcre package.
That would be rather nasty regardless of the library availability.
There should certainly be no need to install pcre to get zsh working.
