[PATCH] ld: depend on libctf

[Stephen Casner]

It seems I am stuck, so if any of you have advice I would appreciate
it.

Switching to gcc10 did not help because the problem is ld.  I have the
MacPorts binutils package installed (2.34 is latest), but I see that
does not include ld.  The ld that I have is:

auge57> ld -v
@(#)PROGRAM:ld  PROJECT:ld64-530
BUILD 18:57:17 Dec 13 2019
configured to support archs: armv6 armv7 armv7s arm64 arm64e arm64_32 i386 x86_64 x86_64h armv6m armv7k armv7m armv7em
LTO support using: LLVM version 11.0.0, (clang-1100.0.33.17) (static support for 23, runtime is 23)
TAPI support using: Apple TAPI version 11.0.0 (tapi-1100.0.11)

I have the binutils sources, of course, in order to build the pdp11
cross, but I can't build the native ld, either.  Is a binary for macOS
10.14 available somewhere?
