[Image-SIG] building pil-jpeg has no symbols

[Calvin]

Just van Rossum provided the following tip to correct the problem of jpeg 
not being built with make. :

>>gcc -o coretest coretest.o libImaging.a -lz  -lm

I modified ImConfig.h too look like this:

/* Define if you have the IJG jpeg library (-ljpeg).  */
/* #undef HAVE_LIBJPEG */
#define HAVE_LIBJPEG 1

Make ran correctly but still gave this error:
ranlib: file: libImaging.a(Dib.o) has no symbols

I'm not sure what Dib.o relates too.  Regardless, after running python 
setup.py build, and python setup.py install, jpeg is now usable in PIL.

Thank you Just.
