 > Adding {{{-fstack-no-check}}} appears the best solution/workaround, at
 least for now.

 I'm not familiar with this flag. Doing this breaks {{{configure}}}
 completely:
 {{{
     # Fix Xcode 11 issue; see https://trac.macports.org/ticket/59467
     configure.optflags-append \
                     -fstack-no-check
 }}}

 What's the recommended approach using Portfile code?
