The debugger fails to build when configure with --python-python=<path>
where <path> is a non-system location. The reason is a warning made
fatal due to the definition of _XOPEN_SOURCE inside pyconfig.h. This
is exactly the same problem as with _POSIX_C_SOURCE, handled in
python-internal.h as follow:
| /* /usr/include/features.h on linux systems will define _POSIX_C_SOURCE
| if it sees _GNU_SOURCE (which config.h will define).
| pyconfig.h defines _POSIX_C_SOURCE to a different value than
| /usr/include/features.h does causing compilation to fail.
| To work around this, undef _POSIX_C_SOURCE before we include Python.h. */
| #undef _POSIX_C_SOURCE
This patch fixes this problem the same way.

commands terminate as a result of an error.

Python scripts to be used by GDB can be stored in that directory,
and will be automatically found by the interpreter when importing them.
This patch also sets up <gdb_pythondir>/gdb as the directory where gdb
submodules can be stored. For now, there is nothing there, but it can
now be added easily without further code changes.
