This is a fixup patch intended to be squashed into the "linux-user:
Provide safe_syscall for fixing races between signalsand syscalls"
patch.
Fix compilation on non-x86-64 hosts by:
* only adding linux-user/host/$ARCH to the include path if it exists
* providing a fallback hostdep.h header in linux-user/host/generic/

Hi Riku; sorry about the compilation failures. I figured that since
you've already taken the series into your queue that a fixup patch
to be squashed in would be the simplest thing. Let me know if you'd
prefer me to just resend the whole series...
thanks
