Nothing stops you from using lisp/obsolete/{tls,starttls}.el , which
will wrap gnutls-cli or 'openssl s_client' for you, although itʼs not
a path I'drecommend.

I think you can configure emacs using '--without-libgmp', then it will
use a builtin version of gmp. Iʼm assuming that linking to libgnutls
only has a runtime dependency on libgmp, not a requirement to have
access to gmp headers.
Maybe just uninstalling libgmp-dev but leaving libgmp installed is
enough?
