add: show more command-line arguments to control which
python is used and where py/pyext files should be installed.
The new options are in addition to the existing PYTHON, PYTHONDIR,
and PYTHONARCHDIR environment variable, providing the help messages
to the user, so it can easily change parameters without second-guessing
of what are they.
Environmental parameters override command line arguments (is it right?)
updated: An extension to Configure.find_command to allow specification
of the name for the searched command (using `msg` option). This is
helpful when the search command is a huge list, as in the case of
python's python-config case.
updated: Do not specify prefix for `get_python_lib`, since this way it
can result in a wrong PYTHONDIR and PYTHONARCHDIR on certain platforms
(e.g., OSX)
updated: Changing logic with byte-compilation of python files. Mow, files are
compiled during the build stage, not install stage. During the
install stage files are simply copied to the requested
location.
updated: If there is an error in python source code, byte-compilation
phase will raise an exception and abort building process.

A list was changed during iteration, causing an unnecessary dependency to be
kept, and triggering subsequent rebuilds. This only occured with multiple .moc included.
gcc, gxx, and fc_config for Darwin platform were specifying
-compatibility_version and -current_version compilation flags. These
flags are actually are link flags and generate warnings by clang
compiler.
Also, these flags were specified in non-standard way, which was
confusing clang compiler.

Chain down to the pre-existing Task.exec_command() implementation if
task.env.CC_NAME indicates that the current taskgen isn't building using
Microsoft tools.
Attempt #2. The previous version (9b443a4e, reverted in 148598a8) was
found in Issue 1243 to lead to unusual infinite regress if the
monkeypatching code executed more than once in a Python interpreter
lifetime. This version uses dynamic subclassing to avoid that problem.
Issue 1237.
