[boost] BOOST_ALL_NO_LIB

Pardon my nit-picking, but I fail to see the relation between BOOST_ALL_NO_LIB spelling and autolinking -- which is exactly what this macro controls. Perhaps this macro has some extra semantics, but I can't find any, except for auto-linking, in separate_compilation.html, nor in library's config.hpp files. Wouldn't it be better if the macro was named BOOST_ALL_NO_AUTOLINK? Thanks, Volodya
