I have `b2 <stdlib>libc++` on CI for Spirit with
https://github.com/boostorg/spirit/blob/develop/.travis.yml#L119-L121
When I tried to make a PR I stuck at the thing that I do not know how (or
it is not possible) to format (free-)future value into some flags, i.e:

> toolset.flags clang-linux.compile OPTIONS <stdlib> : -stdlib=[
value-of-feature <stdlib> ] ;
> toolset.flags clang-linux.link    OPTIONS <stdlib> : -stdlib=[
value-of-feature <stdlib> ] ;

But since in the wild there are two possible options it might be ok to just
hardcode them for now.
