Some third-party projects, such as matplotlib and PIL/Pillow,
depended on being able to build with Tcl and Tk frameworks in
/Library/Frameworks. They were unable to build with the built-in
Tcl/Tk and/or execute correctly.
Make it easier for users to make use of the backup _tkinter linked
with the third-party Tcl and Tk frameworks in /Library/Frameworks.
The two tkinter variants are now installed in separate directories
under a new lib-tkinter. This allows per-user selection by
manipulating sys.path, directly or with PYTHONPATH. If this
proves useful, we can supply a more convenient user interface
to supply the paths. For now, this remains somewhat experimental.

of OPT for special build options. By setting OPT, some compiler-specific
options like -fwrapv were overridden and thus not used, which could result
in broken interpreters when building with clang.
64-bit/32-bit installer for 10.6+. It is no longer necessary
to install a third-party version of Tcl/Tk 8.5 to work around the
problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
and later releases.

1. ppc arch detection for extension module builds broke with Xcode 5
2. ppc arch detection in configure did not work on OS X 10.4
3. -sysroot and -arch flags were unnecessarily duplicated
4. there was no obvious way to configure an intel-32 only build.

- Remove OS X installer and Mac/Makefile dependencies on /Developer which
no longer exists with Xcode 4; the referenced tools have been installed
into the usr/bin tool root since Xcode 3.
- Support adding the SDK usr/bin tool root to the installer's PATH via the
SDK_TOOLS_BIN environment variable.
different parsing of the Makefile by distutils.sysconfig and
sysconfig in the case when an intermediate config vars, used to
construct PY_CFLAGS or PY_LDFLAGS, has a trailing space character.
In this case, the OS X installer build script was leaving a
trailing space in the OPT and LDFLAGS config vars. The space is not
significant and it's not worth toying with the Makefile parsing.
build paths from configuration variables cached in _sysconfigdata.py, as
is already done for the installed Makefile. This avoids a distuils test
case failure in test_ldshared_value.
