[oe] [PATCH] bitbake.conf: BUILD_LDFLAGS: use $ORIGIN in the -rpath rather than a full path.

[Chris Larson]

Yeah, its one of many changes needed to get things relocatable enough
to be able to use prebuilt binaries / packaged staging packages
amongst a group of developers, for example.  This is just one piece of
the puzzle, of course.  Ideally, more open source projects would be
properly relocatable, and we wouldn't need so many hacks.  We ended up
doing a lot of things to work around reloc issues in native/cross
recipes, for MVL6.  Everything from exporting a pile of new env vars
to writing wrapper scripts and the like.. yech.  Still, it's a worthy
goal, and the benefits would be worthwhile, so I think we should start
taking the steps in that direction.
