The patch is necessary for making gcc-for-host happen. It is the second
attempt at solving that part of the problem and I don't particularly
like the patch (though my previous attempt broke something else).

I think there is yet another way of solving that part without patching
gcc at all: Supplying /usr/lib/gcc/<triplet>/<version>/{as,ld} as
symlinks pointing to the triplet-prefixed binutils should be sufficient.
Not having to add another patch should help reduce the maintenance cost.

Given that gcc-for-host is not a thing yet and that there still are
alternative approaches, I'm in favour of just reverting that patch with
no replacement now to unblock your work.
