Hardly impossible though.

You can always have errors in the build processes where some
dependencies lie outside the sysroot, so being able to distinguish the
sysrooted paths is a good thing.  One additional functionality could
be to spot non-sysrooted paths at --mode=finish time, and diagnose
those.

Also, the "=" comes from GCC's syntax, it's not libtool's invention,
and reusing it meant that the sysroot support was much less painful to
add than it seemed.
