    configure uses incorrect link order when testing libpython

    Configure uses "gcc -o conftest -g ... conftest.c -ldl -lncurses -lm -ldl
    ... -lpthread ... -lpython2.7" when deciding whether give libpython is
    usable.

    That of course is the wrong link order, and only works for shared libraries
    (mostly by accident), and only on some systems.

    gdb/ChangeLog:

        PR gdb/11420
        * configure.ac: Prepend libpython.
        * python/python-config.py: Likewise.
        * configure: Regenerate.
