I have been travelling all of April, but it's most probably a few
weeks old as I detected the first symptoms of it before heading out,
back when I assumed it was a problem with a recent change of platform in
my code.

No other library that this codebase currently autolinks [1] exhibits this
behaviour, just System and Filesystem.

I do not believe that this is appropriate for boost-build@, as this is
all about how the library instructs the headers responsible for symbol
decoration and autolinking, not anything that Boost.Build does.
