--- Comment #6 from Tan xc <sterprim at outlook dot com> ---
This has been a lingering issue since the old days. GCC deliberately dismis=
ses
well-known library paths when invoking the linker. When multilib is on, the=
 %D
specifier in the spec automagically inserts library path from multilib opti=
on,
which conceals this problem.

While this logic saves a little parameter size, there is no need to keep sa=
ving
the space of the parameters, since all modern operating systems have a large
enough parameter space (all of them have 262k at least). This prevents GCC =
from
working with other linkers correctly.=
