Hi Eamon! I finally got around to committing your patch, and then
discovered you already did it. :-) Thanks!

Huh. I don't understand why; can you give some rationale?

I don't understand why, but I guess all the .pc.in files are being
distributed even if they're conditionally excluded from EXTRA_DIST. So
`make dist` after configure has been called with some --disable flags
still produces a tarball that can be used when configured with all
extensions enabled.

Which means this is OK, for some reason I don't know.

That seems like the general shape of a solution, yes. (I'd probably use
a simple shell script rather than a Makefile, though, I think...)
Questions remain, though, such as what the .pc file should look like
when generated by this process and how to version the generated
libraries and .pc files.
