[PATCH] D21471: [MCContext] Don't use getenv inside class constructor

[Reid Kleckner via llvm-commits]

rnk added a comment.

Hopefully programs don't start threads during static initialization, so the
getenv call isn't racy with setenv. OTOH, programs that use setenv and
threads are already busted, and we can't really help them.
