I wrote it in 1999, and at the time, that is what worked for me.

EDE actually will use a range of different linkers, and the ld one was
the first match.  If you use:

M-x customize-target RET

you can select a new linker, such as a g++ linker, or the gfortran
linker.  Looking in ede-proj-obj.el (ede/proj/obj.el ?) it is hopefully
obvious how to add new linkers here.  I think my test suite I use uses c
++ instead, and thus gets a different linker.  I apparently need to add
a new test. ;)
