Those are in line to get fixed, but I wanna fix the build-in-tree issues first (which, alas, are harder than you´d think). I suspect that bapt´s src.opts.mk diffs are likely good candidates to be used committed too, but the above works w/o it. Also, I just built the binaries, I didn´t see if they worked.
