 Log Message:
 graphics/graphviz: fix build with BSD make
 
 BSD make does not know the $< variable in explicit rules, it only knows
 it for inference rules like ".c.o".  This resulted in $< expanding to an
 empty string, which in turn got the build stuck because it tried to read
 from stdin.  But not in parallel mode, where stdin was redirected to an
 empty file, resulting in an empty PostScript file being installed.
 
 Fixes PR pkg/55539.
