I am not sure this is the right fix for the problem. I believe the
problem is that the external toolchain wrapper should also wrap "ld" in
order to pass the right arguments to select the correct emulation, just
like we have a wrapper for "gcc" to select the correct architecture,
ABI and so on.

No?
