This may be appropriate for contributed code that will build on older
FreeBSD versions without issues, but I don't like being forced to add
(mostly untested) compatibility code with usage of recent libc features.
For example, utilities like cp and touch currently use
utimensat/futimens without #ifdef mess or extra code in libegacy. The
strict BOOTSTRAPPING conditionals allow removing bootstrap tools
eventually, when building from such old versions as to need them is no
longer supported.
