Subject: 7zip: Increase minimum ELF header length
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=75ef803092e64587449743cacf2ae6e22a515f70;p=thirdparty%2Flibarchive.git

7zip: Increase minimum ELF header length

The 64 bit format requires at least 63 bytes, so increase this limit.
Such small binaries most likely don't contain 7zip data anyway.
