Ken has it exactly right. Since you're making a custom system, it's
entirely up to you whether it's worth supporting multiple
architectures. The LSB, on the other hand, is trying to foster a
standard environment for people to target Linux applications to.
Multiarch makes that standard environment more flexible. Whether you
want your custom system to support this flexibility is entirely up to
you and will most likely be influenced by whether you find it
necessary to support 3rd party binaries that only target a specific
architecture.
