GCC has aarch64 support for stack-clash-protection, but it only works
well with 64K pages (otherwise detection is not reliable).  This is due
to a choice by the target maintainers I do not understand.  At least it
does not break anything.

I don't know the state on armhfp.  It used the generic GCC
implementation in the past, which we considered too buggy to enable.

Thanks,
Florian
