for release builds.
This is a follow-up to r194589. Aaron pointed out that building
libraries with /MT and using them in an application that uses a
different run-time library can be a bad idea.
Move the option to build with /MT behind a CMake option so it can be
turned on selectively, such as when building the toolchain installer.
