Responsibility for setting up implicit library search paths was recently
transferred to the PS5 driver (llvm#109796). Prior to this, SIE private
patches in lld performed this function. During the transition, I failed
to maintain the order in which implicit and user-supplied search paths
were supplied/considered. This change ensures user-supplied search paths
appear before any implicit ones on the link line.
