Dave Nicponski c3c3f68020 xcbuild: add compatibility support for exporting sdk info
"Real" xcodebuild allows using `xcodebuild -version -sdk` without
an sdk version argument, which will dump sdk info for all the
installed sdks.

Bazel"s "xcode cc toolchain setup on mac" process uses this
to determine which SDK version is actually installed.  This
change allows using a nix-supplied pinned compiler and build
system under bazel.
