Or do something along the following:
mv /usr/local/lib/gcc6/gcc/x86_64-portbld-freebsd12.0/6.3.0/include-fixed/ \
  /usr/local/lib/gcc6/gcc/x86_64-portbld-freebsd12.0/6.3.0/include-fixed.not-needed/

Ideally, ports should stop shipping mangled system includes, or even better,
gcc stop doing fixincludes.
