Except that this doesn't happen in my case.

I added an explicit dependency on x86_64-w64-mingw32-crt (both build
and lib, just to be sure) and it's still not being updated before
x86_64-w64-mingw32-winpthreads.

I do have two bootstrapping subports of x86_64-w64-mingw32-gcc (with
suffix -boostrap and -nothreads). But maybe the logic is wrong
somehow?

Note that MacPorts doesn't complain about a dependency cycle and there
were never any issues with that so far (I'm talking exclusively about
existing ports, not about any new ones). The only change I made now
was to add an explicit dependency on -crt (but that didn't really help
in any way, and I'm not sure why not).
