if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.
(which is not) throughout the ports Makefiles.
* Replace find|xargs with find -exec {} +
* Replace -exec {} \; with -exec {} + if applicable.
* Use the -delete operator to remove files and empty directories.
* Combine and tweak some find(1) invocations while here.

compiling Arduino code without the GUI that we won't have to
maintain ourselves anymore.
This replaces the custom Makefile we used to ship in the
devel/arduino port.
