On standard Fedora 14 ./configure (no python options given) I get:
#define HAVE_LIBPYTHON2_7 1
#define HAVE_PYTHON 1
#define WITH_PYTHON_PATH "/usr"

I am not a Python expect but I believe for GDB linked with the only regular
system Python $PYTHONHOME should work, even for GDB-Python.

Maybe it should be overriden only for the case of PYTHON_PATH_RELOCATABLE?
Or maybe only if --with-python=SPECIFIC-PATH has been given?

(I do not have an opinion what it should do in such case, just I think I know
what it should do in the default system Python case.)
