Oh, I thought Andreas was saying there's some problem with the
PKG_CHECK_MODULES macros so they only work when libgnutls-dev is
installed.  Thanks for explaining.

I feel (as Lars does) that GnuTLS should be a required part of Emacs,
disabled by choice.  Today it's hard to imagine a system where you would
not want GnuTLS enabled if it was available for the platform.  In any
case, if a maintainer could give me a definite yes or no, I would
appreciate it.  Switching the default to "no" is not a problem
technically.
