NO_TILE_C => no USE_TILES in tile.c

Compiling with NO_TILE_C defined results in preventing USE_TILES
from being defined and that causes display.c to use alternate code.
Construct src/tile.c such that nethack links successfully if the
configuration specifies NO_TILE_C but the Makefile goes ahead and
builds tile.c, compiles it, and links with it, otherwise it conflicts
with that alternate code.  Prior to this, linking gave two complaints
about duplicate symbols and failed.
