python3: upgrade to 3.7.2

I took the same approach as the recent perl upgrade: write recipe from scratch,
taking the pieces from the old recipe only when they were proven to be necessary.

The pgo, manifest and ptest features are all preserved.

New features:

- native and target recipes are now unified into one recipe

- check_build_completeness.py runs right after do_compile() and verifies that
all optional modules have been built (a notorious source of regressions)

- a new approach to sysconfig.py and distutils/sysconfig.py returning values
appropriate for native or target builds: we copy the configuration file to a
separate folder, add that folder to sys.path (through environment variable
that differs between native and target builds), and point python to the file
through another environment variable.

There were a few other patches where it was difficult to decide if the patch
is still relevant, and how to test that it works correctly; please add those
as-needed by testing the new python.

-Subject: [PATCH] setup.py:check cross_compiling when get FLAGS
-
-Fixed when compile target pythnon3:
-gcc -isystem/path/to/sysroots/x86_64-linux/usr/include \
-    -L=/path/to/sysroots/x86_64-linux/usr/lib
-
-This is incorrect, the native sysroot should not be used by target
-python3.
