Whether this link should be present depends on whether soname has
"1.41" or "1.41.0" at the end. If it has "1.41.0", to reflect the
lack of any BIC between any versions of Boost, then 1.41->1.41.0
symlink is not really necessary.

And whether point releases are required to have any binary compatibility
or not is a tricky question, especially given that "upstream" does not
want any point releases at all.

This might be obvious, but such a soname would be wrong if the above naming
of libraries is used, since there would be no
