9c4ea6c5a9 allow building GDB with Python support on MinGW
This makes several adjustements to the configure python-config.py
scripts to deal with the differences between a Unix install of Python
and a Windows install of Python (as downloaded from the Python website).

Differences:

  - The Python executable is directly in the python prefix directory
    as opposed to inside the bin/ subdirectory.

  - The name of the python library is does not have a dot in the version
    number: On Unix, we have libpython2.7, while on Windows, it's
    libpython27.  So the regexp extracting the python version from
    the Python lib filename had to be adjusted slightly.

    Also, the tests checking the name of the libpython had to be
    adjusted to allow for that.

  - There are no link options following the -lpython<version> switch
    on Windows, but the regexp extracting the python version was
    using it as a delimiter.  It had to be removed.

  - python-config.py does not work on Windows, mostly because
    some sysconfig variables are missing.  They are not necessary
    so the script was adapted to skip them if not defined.

  - The paths returned by python-config.py follow the Windows filename
    convention in terms of the directory separator, and this is causing
    trouble when the build environment is cygwin (while the compiler
    and Python are MinGW).  We could have fixed that in the configure
    script, but it felt simpler to do so in python-config.py

gdb/ChangeLog:

        * configure.ac: Add handling of Python distribution on Windows.
        * python-config.py: If the LIBS, SYSLIBS, LIBPL and/or LINKFORSHARED
        sysconfig variables are not defined, then do not use them.
        On Windows, if LIBPL is not defined, then use prefix + '/libs'
        instead.  On Windows, return all paths using forward-slashes
        rather than backslashes.

7e6e39e562 Resync python-config.py with Python-2.7 version.
This is just a copy of the Python 2.7 version of python-config.py.
Tested with versions 2.5 and 2.6.  It's nearly identical to the
previous version, except it's written in a more pythonic way,
so it should be fine for 2.4 as well.

gdb/ChangeLog:

        * python/python-config.py: Resync with Python 2.7 version of this
        script.
