Yes, this is necessary. I didn't really look into why these work for
arm64 for (Apple) upstream but not on Ubuntu. Are these (iOS devices)
known to be different to our arm64 thingies? I guess an upstreamable
interim workaround would be to (&& PLAFORM(IOS)) these.

I'm sorry but I can't find the place that I got disable-jit-harder.diff
from (should have added patch headers...). From memory I applied it to
resolve build failures with arm64 too. I see that apple and chromium's
trees have this patch, but webkitgtk (webkit.org) SVN doesn't. Was
probably attached to a bug on bugs.webkit.org. I suggest you try without
it and see what happens. If it fails then the error will probably lead
you to the same patch.

Yep.

Thanks. The X-Debbugs-CC was right but I've had some woes on my
mailserver so some messages got dropped on the floor. I guess this was a
victim of that.
