Have `make distclean` also remove .i and .s files

[Gerald Pfeifer]

After using GCC's -save-temps option to debug something, I noticed
that `make distclean` fails to actually remove .i and .s files.

This patch fixes it.  I hope it's the right place to make this change?

ChangeLog:
Add *.i and *.s to CLEAN_FILES.
