Isn't using pkg-config in a GNU project a bit tricky?

In any case, Mozilla does not publish pkg-config data as far as I can 
see, and downstreams probably vary in what they do.  For example, Fedora 
does not provide pkg-config data for libfreebl at all.  You can link 
against NSS, but then you also get libdl and libpthread, which we do not 
want as dependencies of libgcrypt.
