[Debian-med-packaging] Bug#770041: uc-echo: FTBFS on arm64

[Edmund Grimley Evans]

Source: uc-echo
Version: 1.12-7

It failed to build on arm64:

http://buildd.debian.org/status/package.php?p=uc-echo&suite=sid

The error was:

g++ -c -g -O2 -fstack-protector-strong -Wformat
-Werror=format-security -m64 -Wall -O3  -D_FORTIFY_SOURCE=2 DNASeq.cpp
-o DNASeq.o
g++: error: unrecognized command line option '-m64'

In debian/rules there's a big long list of Debian architectures that
don't need "-m64". You can add "arm64" to that list, though you might
want to think about listing the architectures that do need it instead.
