Simon Tatham 5a9e93f39c [clang][Driver] Improve multilib custom error reporting (#110804) ...

If `multilib.yaml` reports a custom error message for some unsupported
configuration, it's not very helpful to display that error message
_first_, and then follow it up with a huge list of all the multilib
configurations that _are_ supported.

In interactive use, the list is likely to scroll the most important
message off the top of the user's window, leaving them with just a
long list of available libraries, without a visible explanation of
_why_ clang just printed that long list. Also, in general, it makes
more intuitive sense to print the message last that shows why
compilation can't continue, because that's where users are most likely
to look for the reason why something stopped.
