python-config.sh ignores the first argument if it's a *.py (2.7.3 & 2.7.4 only)
bugfix for 'python-config.sh --ldflags' lib folder (2.7.x so far)

We were not returning the config folder (which contains

Don't define MS_WIN64 if it's already defined in pyport.h

Also regenerated the patches for 2.7.3 and 2.7.4
