4.9.0 apparently had it's 3rd birthday last weekend ;-)
Also there are quite some bugfix releases meanwhile (4.9.4 being the
latest). And given that arm64 is a rather young architecture, a three
years old compiler is probably bad in many other ways.

So I won't invest much time in getting this particular compiler to work,
but instead rather push kernel.org to update their cross compilers. I am
about to test build GCC 6.3.0 based on the buildall script they use.

I see that there is ongoing effort to get code size down, maybe that
helps here as well, without upgrading compilers.

If you have a particular build test setup, is there any chance you can
try to install a newer compiler there? Linaro offers up-to-date compiler
packages, also distributions offer packaged cross-compilers for arm64
these days.

Cheers,
Andre.
