pkgsrc print/ghostscript fails to build under amd64 dragonfly

[Ed Berger <nobody@xxxxxxxxx>]

got the error to try compiling with -fPIC when building on amd64 release

so I ask please add the following to the pkgsrc Makefile around line #59

CFLAGS.DragonFly= -fPIC

alongside the similar lines for netbsd, linux, sunOS

unless there's something terribly wrong with that idea, and you have a 
better solution....

Thanks!
