Subject: [PATCH] [CMake] Support symlinks with the same name as the binary
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This supports creating symlinks to tools in different directories than
the tool is built to. This is useful for the LLDB framework build which
I’m sending patches for shortly.
