It's a potential dependency for TIFF:

LOC_CHECK_LIBS(tiff,TIFFOpen,TIFF,$TIFF_LIBRARY_DIRS,TIFFLIB,,,,$JPEGLIBPATH $JPEGLIB,$ZLIB,$MATHLIB)

Also, I've been considering writing r.in.jpeg for a while. It might be
useful to be able to import JPEGs with significantly less interference
than occurs when using GDAL (in particular, creating raw, unscaled YUV
layers).
