Pull up following revision(s) (requested by mrg in ticket #552):

	sys/arch/vax/vax/machdep.c: revision 1.198

vax: set default RLIMIT_AS to the same as MAXDSIZ
this allows modern GCC to run without returning to the issues that
reported in PR#28379, and avoids a strange sort-of-invariant violation
where the rlimit for data equaled the rlimit for all address space, so
there is no room for text or stack etc.
