Comment (by kencu):

 {{{thread_local}}} always implies {{{std=c++11}}} or greater.
 <https://en.cppreference.com/w/cpp/keyword/thread_local>

 I had a conversation with Marcus about whether setting
 {{{compiler.thread_local_storage yes}}} should imply at least
 {{{std=c++11}}} and that was felt to be completely unacceptable and it
 should always be separately specified, so therefore you have to specify
 both.

 don't forget that many build systems will test for certain standards and
 use them if available. Just because the build line indicated
 {{{-std=gnu++14}}} on this particular system, it does not necessarily mean
 that  the software actually requires that. Just that it used that during
 this build. Not a big deal -- it will probably just mean that ports that
 might have built with an older compiler will be forced to build with a
 newer one, but I know you don't like that.
