pkgtools/digest needs snprintf() to compile, which IRIX 5.3 does not
have. Fortunately libnbcompat provides that function.
Adding

.include "../../pkgtools/libnbcompat/buildlink3.mk" # for snprintf()

in pkgtools/digest/Makefile nicely solves the issue. Now I am wondering
whether this should simply be done unconditionally. Could this add
unnecessary code for other OSes? Or is there some clever mechanism in
libnbcompat to prevent this?
