* debian/patches/efi_arch_ia32.patch: Use AC_CANONICAL_HOST, not uname -m, to determine target. Closes LP: #1066038. * debian/patches/Align-signature-data-to-8-bytes.patch: Align signature data to 8 bytes. This matches the Microsoft signing implementation, which enables us to use sbattach to verify the integrity of the binaries returned by the SysDev signing service. * debian/patches/update_checksums.patch: make sure we update the PE checksum field as well, also needed for matching the Microsoft signing implementation. * debian/patches/fix-signature-padding.patch: fix calculation of the size of our signature data, so that we don't write out extra zeroes when we detach a signature.
