[Debian-med-packaging] uc-echo: build-dep on g++-multilib

[Roland Stigge]

Hi,

I noticed that uc-echo can't be built on platforms without g++-multilib
(like powerpcspe) because of the build-dependency on g++-multilib.

Further, -m64 is forced as a compiler option to enable allocating >4GB
of RAM.

Would it make sense to enable build on platforms without -m64 being
unavailable (as on powerpcspe), or does uc-echo only make sense with
>4GB RAM allocations?

For the former case - I removed build-dep:g++-multilib and -m64 to make
the package build on powerpcspe.

Thanks in advance,

Roland
