bpo-28552, bpo-7774: Fix distutils.sysconfig if sys.executable is
None or an empty string: use os.getcwd() to initialize project_base.
Fix also the distutils build command: don't use sys.executable if
it's evaluated as false (None or empty string).

'scripts-%d.%d' % sys.version_info[:2])

+Fix :mod:`distutils.sysconfig` if :data:`sys.executable` is ``None`` or an
+empty string: use :func:`os.getcwd` to initialize ``project_base``. Fix
+also the distutils build command: don't use :data:`sys.executable` if it is
+``None`` or an empty string.
