Hello Lintian maintainers,

There are several bugs here
1) not all files ending by '.a' are 'ar' archive files, and this is not
an error.

2) 'unpack-message-for-orig' is used to report error when
unpacking the orig.tar.gz tarball. This is unrelated to what happen here
(an error of "ar" while inspecting binary package), so this tag is
inappropriate.

The combination is a large set of false positive with inappropriate
error messages, just check

https://lintian.debian.org/tags/unpack-message-for-orig?version=2.114.161

Thanks for maintaining Lintian!
