Subject: pysetup.mk: Run commands on multiple `python's, possibly in parallel.
X-Git-Url: https://git.distorted.org.uk/~mdw/catacomb/commitdiff_plain/0ebebfc000cec6d2f974f26074bc6ff3c7f304d7?hp=0ebebfc000cec6d2f974f26074bc6ff3c7f304d7

pysetup.mk: Run commands on multiple `python's, possibly in parallel.

Most targets delegated to `setup.py' are now run, in parallel, on
multiple Python versions listed in the new Makefile variable `PYTHONS'.
The exceptions are `gen' and `dist', which only make sense with a single
Python.

Targets which can run multiple Python versions now support per-version
options for targets: set the variable OPTS-TARGET/PYTHON (e.g.,
`OPTS-install/python3.5').
