Subject: [PATCH] macvim: fix build after Darwin SDK update
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MacVim needs to use the system Xcode to build. Having `DEVELOPER_DIR`
set in the environment causes Xcode to try to use the nixpkgs SDK, which
doesn’t work. Unsetting it allows MacVim to build.
