[issue16262] srcdir != builddir builds fail, if hg is not installed

[Matthias Klose]

New submission from Matthias Klose:

seen with the 3.3 branch and the trunk:

also, I think using python now unconditionally breaks the cross builds, so this should call PYTHON_FOR_BUILD, not python.

/bin/mkdir -p Include
hg: no-repository, python: found! cannot run ../Parser/asdl_c.py -h Include ../Parser/Python.asdl
/bin/mkdir -p Python
