Pass --verbose to linker and see what's in the linker script it uses.
I suspect the issue may be somewhere there.
You can then tweak the linker script, put .interp in the right place
and pass the new script to linker with -T.

That should get you by until proper toolchain fix is available.

I've done a fresh update and rebuilt everything including the toolchain. Is there something missing from my system? The loader itself? Libraries? An ldscript file?
