Re #2059 (misc):

• Allow USE_PYTHON3 to be obtained from environment variable.
• Change PYTHON_EXE. Reasons:
• The platform Arch Linux defaults to Python 3 already. Therefore, when /usr/bin/python is called, it is not Python 2.7 but Python 3.6.
• The platform NetBSD and Gentoo Linux does not offer /usr/bin/python3 but only /usr/bin/python3.6.

Thanks to Alexander Traud for the patch.
