[pkg-go] Bug#802507: runc: FTBFS on non-amd64: undefined: jumpEqualTo et al.

[Aaron M. Ucko]

Source: runc
Version: 0.0.3~dfsg2-1
Severity: important
Justification: fails to build from source

Builds of runc for architectures other than amd64 have been failing:

# github.com/opencontainers/runc/libcontainer/seccomp
src/github.com/opencontainers/runc/libcontainer/seccomp/filter.go:93: undefined: jumpEqualTo
src/github.com/opencontainers/runc/libcontainer/seccomp/filter.go:95: undefined: jumpNotEqualTo
src/github.com/opencontainers/runc/libcontainer/seccomp/filter.go:97: undefined: jumpGreaterThan
src/github.com/opencontainers/runc/libcontainer/seccomp/filter.go:99: undefined: jumpLessThan
src/github.com/opencontainers/runc/libcontainer/seccomp/filter.go:101: undefined: jumpMaskEqualTo

The issue appears to be that these functions are defined only for that
architecture (by .../jump_amd64.go), but then used unconditionally.
Could you please take a look?

Thanks!
