(I forgot to CC the list before)

Yes, I'm already setting my LD to an absolute path. That has no effect though, 
because bsd.wrapper.mk will currently *always* do a PATH based lookup of 'ld', 
ignoring whatever LD was set to before. That part IMO is wrong - one should be 
allowed to prefer a link regardless of which 'ld' comes up first in PATH.
