The problem here is a quick patch makes the situation worse rather
than better.  That is the reason why the quick patch is rejected.

The simple answer is testing, you should be build the multi-libs which
are there for your target that means 32bit for x86_64.  If you don't
want them, explicitly disable them.  The defaults are there for the
majority of users and majority of users of compiling a compiler knows
the risks of not having the current libraries installed.

That is because it is a hard to do and will force extra time in
compiling and might cause incorrect handling of cross builds.
Remember the host compiler does not have to compile for the multi-lib;
only the newly compiled compiler will be able to.
