I don't think we need to support this sice the user can already hide any
symbols with linker scripts.
Also, a thing to note is that I think there are a few places where Boost
relies on some symbols being defined by user, which means they should be
either defined in the same executable or exported from another. For
instance, tss_cleanup_implemented from Boost.Thread works like this.
