[PATCH] Zorg: getLLDBuildFactory() now takes an optional 'env' parameter

[Mikael Lyngvig]

The patch has been updated and I am re-submitting everything I've submitted
to Galina as well so that it goes through a full peer review.

Phew, thank you a ton for catching that!

As far as the CC and CXX environment variables goes, I did it to retain
backwards compatibility with the existing three LLD builders:

-                               env={
-                                    'CXX': "clang++",
-                                    'C':   "clang"},
+                               env=merged_env,

So they already got overriden, I have simply made the override overriddable
:-)  Now you can specify that you want to use ccache in the env argument,
something you could not do before.  I am also going to use ccache.  I bet
your lld builds haven't been using ccache, even if you thought they did.

Please also notice that my builder uses GNU Gold - also through an override
of env.
