Have a look in this line ...

 
https://git.rtems.org/rtems-source-builder/tree/source-builder/sb/windows.py#n56

.. and remove line 57 and make line 58 'host_triple = build_triple' so 
the host and build names are the same by default.

If this works you might then be able to remove line 53 and allow 32bit 
or 64bit.

Note, a user can always cross-compile for MinGW with cygwin using --host 
command line option so nothing is lost with this change.
