With MacPorts boehmgc (when built as a standalone library) installs three files:
    /opt/local/lib/libgccpp.1.dylib
    /opt/local/lib/libgccpp.a
    /opt/local/lib/libgccpp.dylib
and those files are probably used when you ask for "-lgccpp", while I
don't find any such files when building gc from within asymptote. I
see libgc.a, but I also see that the configure.ac file is refering to
that file a couple of times.

If you can explain why gc doesn't create libgccpp.a, maybe we can
figure out what the logic should be?
