The error used to look like this:

  ld64.lld: error: undefined symbol _foo
  >>> referenced by /path/to/bar.o

Now it displays the name of the function that contains the undefined
reference as well:

  ld64.lld: error: undefined symbol _foo
  >>> referenced by /path/to/bar.o:(symbol _baz+0x4)

I plan to use debug information to provide even more context in a future
commit.
