arcconf links to libstdc++.so.6. An ancient  libstdc++.so.6 version was provided with old freebsd versions (included with an old gcc). 
The binary failed to run with:  ld-elf.so.1: /usr/lib/libstdc++.so.6: version GLIBCXX_3.4.11 required ..

Newer gcc versions from the port provided  libstdc++.so.6 with >= GLIBCXX_3.4.11. 
Thats the reason why gcc was added.
