Subject: OpenBSD has two stdc++ libraries: use the newer
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=2c39ee12a99f9548a5e379e8bcea4f7923028fee;p=rust.git

OpenBSD has two stdc++ libraries: use the newer

stdc++ is from base, and is an old library (GCC 4.2)
estdc++ is from ports, and is a recent library (GCC 4.9 currently)

as LLVM requires the newer version, use it if under OpenBSD.
