Rudi Heitbaum d17947e802 Fix missing symbols as libtiff can depend on libjpeg 
when compiling Pillow with libtiff and libjpeg (with jpeg12 enabled -
which is the default with libjpeg-3.0.0) the libtiff object
tif_jpeg_12.c.o uses the following libjpeg12 functions:
jpeg12_read_raw_data, jpeg12_read_scanlines, jpeg12_write_raw_data,
jpeg12_write_scanlines.

update the ordering of libs.append(feature.tiff) to be before
libs.append(feature.jpeg) to allow the linker to include the required
functions.

this issue occurs when the libtiff and libjpeg libraries are static
(not shared.)
