We could make this work if we truly wanted to.  It just seems like a lot
of effort; and building gdb is not so very hard.

The other day I was thinking we could even automate it by reading the
libpython debuginfo to generate weak declarations for the public API :-)
But, ok, that is not practical for regular gdb builds.
