Make distutils error messages more helpful (#11599).
When running external programs such as a C compiler and getting an
error code, distutils only prints the program name. With this change,
one can get the full command line by setting the DISTUTILS_DEBUG
environment variable.
This should have no compatibility issues, unless there are tools
that depend on the exact format of distutils debug messages.
