I'd need to see exactly how do_install is working to be sure - generally,
anything that do_populate_sysroot is able to process must have been
installed during do_install. I would imagine what's happening is that 
${B}==${S} and the entire contents of ${S} is being installed to ${D} and 
thus if the symlinks are present in the source tree, they get installed.

Even in the absence of this issue I would recommend that you check
what's going on during do_install because if what I described above is the
case, it's possible it is installing a whole bunch of files that it shouldn't be.

Cheers,
Paul
