depends: always configure with --with-pic

We currently do this sporadically. Not only amongst packages, but across
OS's, i.e sometimes it's done for BSDs/Android, and sometimes not.

Configure with `--with-pic` globally instead. I think this generally
makes more sense, and should not have any downsides.
