Interestingly, this issue does not seem to affect all architectures.

On sh4 (which is Zero-only), for example, openjdk-9 builds fine
despite being built with --with-debug-level=release [1].

So far, it's only m68k and powerpc which are affected (and presumably
powerpcspe as well which is powerpc just without FPU and Altivec).
Also, as we're building Zero on the Hotspot architectures as well and
it works there with release debug level as well.

Thus, I suggest only switching the debug level to slowdebug on m68k,
powerpc and powerpcspe:

Attaching patch.

However, before applying this, let me test whether this might resolve
by building openjdk-9 with gcc-7. We've seen gcc-6 miscompiling code
where gcc-7 worked fine [2].
