This is the first pretest for what will be Emacs version 27.1. It is not
intended to be committed to the ports tree until 27.1 is released.
Port changes:
- depend on math/gmp
- match upstream by turning CAIRO, HARFBUZZ, and JSON options on and turning
MAGICK off by default
- remove OPENMP check for graphics/ImageMagick as the openmp is now
included in base
- update EMACS_VER in Mk/Uses/emacs.mk
- bump USES=emacss port or remove BROKEN for net-im/jabber.el and deskutils/howm,
which now builds
