A new update to clang is causing warnings (which are errors because edk2
was Werror by default).  The error is:
clang-15: error: '-x c' after last input file has no effect [-Werror,-Wunused-command-line-argument]

Work around it by disabling this specific error.  Also, use devtool to
update the patch.
