[hpsdr] working with ghpsdr3

[Chris Smith]

Dave

I've successfully built ghpsdr3 under Fedora 15 x86_64 without too much problem. There is a minimal amount of editing of the Makefile to reflect the x86_64 library directory in the -I & -L stanzas but otherwise all built without a hitch.

Cheers & 73
