Recall, we're talking about --layout=system, which is explicitly meant for
system integrators. So it's not a "small suffix", it is "incompatible with
system naming of libraries". There is zillion ways to compile any library,
so this matter is not specific to boost.

It is known that compiled versions of some Boost libraries have different ABI
in ST and MT mode. But then, Boost is not one library of such kind.
