Alright, this works now.

I'm using Pjotr's patch
https://gitlab.com/genenetwork/guix/commits/ldc-1.14-20190222/gnu/packages/dlang.scm
to build ldc 1.14, but I hit the opposite issue of what was initially
described in this post:

- It does not seem to build against gold, it seems to use the regular
  binutils.
- Tests fail because they can't find 'ld'.

The first failing test is:
--8<---------------cut here---------------start------------->8---
         1552/1587 Test #1552: druntime-test-aa ...................................................................***Failed    0.49 sec
         make[1]: Entering directory '/tmp/guix-build-ldc-1.14.0.drv-0/ldc-1.14.0/runtime/druntime/test/aa'

         collect2: fatal error: cannot find 'ld'
         compilation terminated.
--8<---------------cut here---------------end--------------->8---

I don't really understand how it can fail to find 'ld' considering it's
supposed to be building with binutils.

Am I missing something?  Pjotr?
