Re: unbreak devel/gmake on armv7

Ok, so here is a correct patch.
The problem is that makeint.h considers that __arm is not really
POSIX.1 compliant. I think it was meant to only apply to SVR3 ?
But any variant that fixes the condition on OpenBSD is ok.

I've left the patch for the missing semi-column in place, although
this code should never be used.
