x11/xfce4/xfce4.port.mk: add a git link to false in ${WRKDIR}/bin
for ports using meson, the meson.build files try to generate
xfce-revision.h from git rev-parse --short HEAD, which:
- is a hidden BDEP on devel/git
- is useless since we don't build from git checkouts
and if dpb junks devel/git after configure, the build fails.
so add the link to make 'git' always fail, instead of adding a useless
BDEP on devel/git.
found the hard way by claudio@ while fixing a metric ton of things on sparc64
looks good to tb@
Switch to ports-gcc
