Ahh. That helps explain the use of "native" in devel/binutils and
why it is listed first and that there is a matching default, from
looking . . .

FLAVORS=        native aarch64 aarch64_none_elf amd64 arm_gnueabi arm_none_eabi \
                avr i386 mingw32 mips mips64 powerpc64 riscv64 s390x sparc64
FLAVOR?=        native

Looks like that makes testing for the default (or literal native here) testable:

.if ${FLAVOR} != native

So adding an extra flavor as a default could allow for generating an error?

Thanks for the note. It helped me understand what to expect and what to watch
out for.
