Comment (by ryandesign):

 Also be very sure that you are only increasing the revision of the
 subports that would actually change. For example, if it is the llvm-18
 port whose contents would change, increase the revision only of the
 llvm-18 subport, not of the mlir-18, clang-18, lldb-18, and flang-18
 subports. Or, if this .xctoolchain file ends up getting installed by the
 clang-18 subport, then increase the revision of only that subport, not the
 others.
