The "raster" directory has an HTML file (rasterintro.html), and the
%.html rule tries to install the r.in.png and r.out.png "images". The
install program treats it as an error if you try to install a
directory.

I modified raster/Makefile to include explicit dummy rules for these
targets, to override the normal rules for anything ending in .png.

FWIW, this approach has been committed as r48561.
