julia: link fails for 10.14 and earlier: ld: unsupported tapi file type '!tapi-tbd' in YAML file

[githubbjs (BJS)]

This port is failing to build for 10.14 and earlier, with the following link error:

ld: unsupported tapi file type '!tapi-tbd' in YAML file 'work/julia-1.8.0/src/mach_dyld_atfork.tbd' for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

kind of an unusual error:

Failed to build julia: ln: /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_julia/julia/work/bin/gfortran: File exists

I'm also getting an error on Mojave (10.14.6). I first saw this with port upgrade outdated but the error continues after an uninstall/reinstall cycle. I don't think the gfortran message is the root cause. In my log and the log from githubbjs I see:

:info:build ld: warning: text-based stub file /opt/local/var/macports/build/_opt_local_var_macports_
sources_rsync.macports.org_macports_release_tarballs_ports_lang_julia/julia/work/julia-1.8.0/src/mach_dyld_atfork.tbd and library file /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_julia/julia/work/julia-1.8.0/src/mach_dyld_atfork.tbd are out of sync. Falling back to library file for linking.

My first attempt doesn't have a gfortran error, but if I run port install julia a second time without port clean julia then I get the following error:

gfortran in the work/bin directory is a symlink to /opt/local/bin/gfortran-mp-12.
