Subject: [PATCH] stdenv: fix evaluation if !stdenv.cc.hasCC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

stdenv.cc may throw, e.g. in the case of pkgsCross.ghcjs where we must
not force it for the purpose of attribute accessing (`or` doesn't
implicitly tryEval…).

Regression introduced in 1a5bd697adecf27385b69352485baa52a6e02fe9.
