For the .so file, the difference is in the file name that appears in the
.gnu_debuglink section (created by the ‘strip’ phase):

Most likely this is because ‘strip-dir’ in gnu-build-system.scm
traverses files in unsorted order, and thus can pick one or the other.
The other file has a timestamp issue:

For reference, a discussion of the responsible code:
https://groups.google.com/forum/#!topic/linux.debian.bugs.dist/hjzVpYKCbr0
Unfortunately, that code ('doc/yat2m.c') is different across the various
GnuPG projects, so we can not take the patch directly from gnupg-2.1.
