gcc issue building -current

Hey folks,

I can't cross build -current VAX (from a -current amd64 machine), it
dies with an internal gcc error trying to build lint. The tools build of
lint works, but the vax build fails:

dependall ===> lint1
#   compile  lint1/cgram.o

Stop.

The build cluster has not run into this yet, so I suppose a recentish lint
change in -current triggers this.
