I realize that GCC 5.3.0 may require a newer linker than the default in Xcode for Tiger, but even if I select GCC 4.0.1 as the current compiler, ld still invokes /opt/local/bin/ld.

Tiger is so old that all the compilers included in its Xcode are too old and buggy for MacPorts to use. So MacPorts installs and uses the apple-gcc42 port and uses that compiler to build all ports on Tiger (unless a port specifies otherwise). The apple-gcc42 port requires the ld64 port, which is where /opt/local/bin/ld comes from. You should probably use /opt/local/bin/ld and the gcc installed by the apple-gcc42 port, even for things you compile on Tiger outside of MacPorts, rather than the ancient versions that come in Tiger's Xcode.
