I have removed the reST target I added in 38cdca2cc253: it is not necessary, as
people can link to the glossary entry or the abc module without it.

Two indentation fixes from 3.2 collections.rst have been ported to 3.3
collections.abc.rst.

The tests now pass all combinations of -O/-OO and -B.  See also #7071
and #6292 for previous variations on the same theme.

test_versionpredicate needs a skip when sys.flags.optimize is true, but
I don’t know how to make that work with a DocTestSuite.

build_scripts command of packaging now handles correctly non-ASCII path (path
to the Python executable). Open and write the script in binary mode, but ensure
that the shebang is decodable from UTF-8 and from the encoding of the script.

(merge from 3.2) Issue #9516: avoid errors in sysconfig when MACOSX_DEPLOYMENT_TARGET is set in shell.

Without this patch python will fail to start properly when the environment
variable MACOSX_DEPLOYMENT_TARGET is set on MacOSX and has a value that is
not compatible with the value during Python's build. This is caused by code
in sysconfig that was only meant to be used in disutils.

longer fails if zlib is not installed. Instead, the zipfile.ZIP_STORED
compression is used to create the ZipFile. Patch by Natalia B. Bidart.
