This adds a new binary, `swift-backtrace-static`, to the build. The runtime will not by default use this binary as the backtracer, but if you want to statically link your own binaries against the standard library you can copy `swift-backtrace-static` rather than `swift-backtrace` alongside your binary, naming it `swift-backtrace`, and the runtime should find and use it, which will mean you don't need to have `libswiftCore.so` et al installed. rdar://115278959
