Comment (by Erik Schnetter):

 Cactus expects LD to be the C++ compiler driver to be used for linking,
 not the linker. In other words, setting LD to "ld" is almost guaranteed to
 be wrong, and setting it to the value of CXX is a good default choice.
 Since the Cactus definition of LD goes against the grain of what LD means
 everywhere else (e.g. in autotools), handling this problematic case
 generically is better than applying a NixOS-only solution.
