The entry in the DEVELOPERS file was missing.

Alphabetic ordering was not correct, and this is reported by "make
check-package".

The Config.in comment for the !BR2_STATIC_LIBS dependency was missing.

The SPDX encoding for this license is CC0-1.0, and the license is in
fact CC0-1.0 or Apache-2.0, as explained in the LICENSE file that
you're using in LIBARGON2_LICENSE_FILES.

I have moved the OPTTARGET=$(GCC_TARGET_ARCH) into LIBARGON2_OPTS, only
added it when GCC_TARGET_ARCH is non-empty, and added a comment to
explain why this is needed, as it is quite odd.

I've applied to next with those changes.

Thanks!
