Comment(by kyle-macports@…):

 Actually, having added `-m64` to the configure flags, the compiler then
 proceeds to error out in a new way.

 Checking on libiberty.a reveals:

 }}}

 I have no idea why gcc is building TWO copies of libiberty, much less why
 it's building one of them without the CFLAGS that the rest of it is built
 with... but that's what's going on. I'm attaching a full debug log.
