Log message:
devel/py-dm-tree: Fix jobs.

1. Use MAKE_JOBS, not the number of CPUs Python detects.

2. Explicitly use tool gmake, which this seems to assume of `make'.

Should resolve, with (e.g.) MAKE_JOBS=4:

Should be no change if the build succeeds, so no revbump.

py-*: remove unused tool dependency

py-setuptools includes the py-wheel functionality nowadays

py-dm-tree: added version 0.1.8

tree is a library for working with nested data structures. In a way, tree
generalizes the builtin map function which only supports flat sequences, and
allows to apply a function to each "leaf" preserving the overall structure.
