Unfortunately not.  This forces a dependency on lpthread even when
it is not necessary (either Python is not built in, or Python is built
without thread support).

This should be handled at the python-config.py level. Something's
wrong, because the script is querying the sys and sysconfig modules
to get the list of libraries that libpython depends on:

What does the following script print with the Python you are using
to link GDB against?

    | from distutils import sysconfig
    | getvar = sysconfig.get_config_var
    | getvar('LIBS')
    | getvar('SYSLIBS')

The output should contain -lpthread if indeed libpython depends
on it (we haven't attempted to build GDB with Python on mips-irix
yet, but we build Python without thread support anyways).
