[Debian-med-packaging] Bug#727657: unconditional build dependency on g++-multilib

maybe the better way would be to list all architectures that support
g++-multilib.
For sid those architectures are:  amd64, i386, kfreebsd-amd64, mips,
mipsel, powerpc, ppc64, s390x, sparc, sparc64, x32
For example, g++-multilib [amd64 i386 kfreebsd-amd64 mips mipsel powerpc
ppc64 s390x sparc sparc64 x32]

Mips doesn't support neither "-m64" nor "-m32" options.
For MIPS64 you should use -mips64 -mabi=64.
For MIPS32 you should use defaults options.
