[Docker-maint] Bug#784543: [pkg-golang-devel] Bug#784543: golang: test failures on arm64

[Michael Hudson-Doyle]

Hm, it bootstrapped fine using gccgo-5 in Ubuntu:
https://launchpadlibrarian.net/214911501/buildlog_ubuntu-wily-arm64.golang_2%3A1.5~rc1-0ubuntu1_BUILDING.txt.gz.
I don't know enough about sbuild to know what the issue is here
(aspcud- vs apt-based resolver?)

The "not found in multicast rib" failure is
https://github.com/golang/go/issues/11936 ("net:
TestIPv4MulticastListener fails on linux without
CONFIG_IP_MULTICAST"), it's a bug that it's not skipped if the kernel
you are using doesn't support multicast. (Which kernel/board are you
using?)

TestCloneNEWUSERAndRemapNoRootDisableSetgroups always fails for me in
a chroot. I should figure out why at some point...

Not sure about the gdb test, but I do know that one is a bit temperamental.

Cheers,
mwh
