* drop all distutils patches, distutils is gone
* drop all setup.py patches, that's gone too
* refresh the 32bit rebase (things changed, but I added
it to the same make target, hopefully still works)
* adjust the new module building code to depend on the import
lib and also add the build dir to the library path so it can
be found.
* ctypes dropped vendored things, so remove code deleting it
* the code printing a warning if a module build fails no longer
exists, so drop the "tee" stuff and the error check there
The main change here is that sys.platform == 'cygwin', which allows
us to drop various changes for extending cygwin checks. Fewer patches
and less likely that we miss to patch a new cygwin check on updates.
If one really needs to check for msys Python then this still works:
sysconfig.get_platform().startswith("msys")
