Comment (by erikd):

 I grabbed the same compiler from
 http://ftp.us.debian.org/debian/pool/main/g/ghc/ghc_7.10.2-2_armhf.deb and
 compiled up a "hello world" program. The compiler worked fine as did the
 resulting executable.

 I inspected the file `/usr/lib/ghc/settings` and found:

 {{{
  ("C compiler link flags", " -fuse-ld=gold -Wl,-z,noexecstack"),
  ("ld command", "/usr/bin/ld.gold"),
  ("LLVM llc command", "llc-3.5"),
  ("LLVM opt command", "opt-3.5")
 }}}

 which is exactly as I expected.

 Here are the versions of llvm/binutils/gcc that I have on my machine:

 {{{
 llvm-3.5      1:3.5.2-1  armhf      Modular compiler and toolchain
 technologies
 binutils      2.25.1-1   armhf      GNU assembler, linker and binary
 utilities
 gcc           4:4.9.2-4  armhf      GNU C compiler
 }}}

 @Ansible, please check your versions of the above.
