Well, on Linux applications are always linked against one architecture
only (or noarched), i.e. multilibs are not of any importance, here.

Multi-arch'ing (The ability to run "non-native" application; e.g.
running ix86 binaries on x86_64) can be relevant in some cases.

However, in practice, such cases are rare. Apart of applications which
lack full "native support" (e.g. firefox plugins), the only cases I've
encountered so far is packages containing library testsuites/example
applications. To package them, %libdir/... seem to be the only viable
option.
