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.
