so might use something like (assuming -B static also holds for sunpro):

.if ${PKGSRC_COMPILER} == "mipspro" || ${PKGSRC_COMPILER} == "sunpro"
LDFLAGS+=	-B static
.else
LDFLAGS+=	-static
.endif

in the toplevel Makefiles of statically linked shells. I think this is the
most transparent way. Maybe it would be nicer to use some case statement?
