With the CLANG38 toolset (clang version 13.0.0) MdePkg fails to build in RELEASE mode because Status is only used by an assert.

Hi Rebecca,
GCC added -Wno-unused-but-set-variable back in 2016 for RELEASE builds to address this same issue
https://github.com/tianocore/edk2/commit/20d00edf21d2f2144921622891d8b59a1553cd83
Then later added -Wno-unused-const-variable
https://github.com/tianocore/edk2/commit/8b6366f8758426fd6710646574b9a7e583e0fe0d

Mike,
That sounds like the right fox to me. Disable the warning.
