I've added two variables to the Makefiles:
 - WITH_TIFF: toggles compilation with tiff support (defaults to true, set to 
false to disable tiff support)
 - NAN_TIFF_LIBS: linker flags for tiff libs, defaults to 
$(NAN_TIFF)/lib/libtiff.a, statically linking against tiff. For dynamically 
linking against libtiff you can set this to something like "-ltiff" in user-
def.mk
