It won't.  Typically, the compiler overrides these anyway.  This is
just meant to overrides the /usr/lib used by default, when the linker
is invoked directly.

Agreed, but note that this was just moved from both of the elf64*.sh
files.

Formerly a cross from i386-linux-gnu to mips-sgi-irix6 would have the
same problem.  If it wasn't a problem for irix, why would it be a
problem for mips-linux-gnu?

Yeah, I agree it's not ideal, but I think it's an improvement over
what was there.  The only negative effect of this change is that a
cross compiler may now look for libraries in a location where it won't
find libraries for the target system.  It will do so after searching
any directories listed in the command line, so it would have failed
one way or the other.
