As Dmitry pointed out you should now be able to drop both -flto-
partition=none an -Wno-error=stack-usage= (the linker will still warn,
but not error on the large stack-usage issues (we should probably still
fix them though).

What do the test results look like? Do they all PASS with -ffat-lto-
objects?

Could you try the proposed patch for

Thanks,
