This is fundamentally the same issue that dpkg has (CVE-2015-0840).
The major exception being Lintian never made attempts to validate the
signature and therefore it is less problematic that it can be
"tricked".
data/.../arch-regex: Correct regex for armhf and armel (static)
Statically linked ELF binaries have a different "file(1) signature"
than we expected on armel and armhf. Particularly, the "(SYSV)"
becomes "(GNU/Linux)" - the reason is not apparent to me, but
fortunately the fix is trivial.
