Have you tested whether the cross-built libtool then works on the target

libtool is part of architecture cross bootstrap since a very long time.
Since about 10 years, it is being cross build (with hacks) in
https://wiki.debian.org/HelmutGrohne/rebootstrap. This patch is a step
towards removing those hacks, so yes, this has been tested for a quite
long time.
Ok, i'm happy to upload. Its on the debian/trixie branch on salsa now.
debian/latest is/was some work on the new 2.5.3 release not ready for
upload.
I was not aware of gfortran-for-host. I would like to explore this more
fully for dh-fortran-mod, but I will continue that in another thread.
This is kinda expected. The whole *-for-host thing is quite recent in
Debian timelines. The concept was first used by qt5-qmake (without the
-for-host naming), later transferred to binutils, eventually reached
pkgconf (without -for-host) and just this year reached gcc-VER and
gcc-defaults.
Please don't change dh-fortran-mod just yet. I also want to see it
there, but we need to be more careful there as it is not as isolated as
in libtool. Just days ago I started a discussion
(https://lists.debian.org/debian-cross/2024/11/msg00000.html) where I
explored cross building fftw3 and quickly ended up at dh-fortran-mod and
a non-trivial problem. I would very much welcome your input there. The
underlying problem is of general nature and Fortran just happens to be
affected earlier than others. Can you tell me what list I should have
Cced for that discussion to reach you?

Agreed. dh-fortran-mod is a work in progress to support multiple Fortrans.
I've been experimenting and testing in experimental and
dev-multi-fortran branches for a bunch of packages, but the overall plan
is not ready for prime time. I had hoped it would be mature enough to
show at Debconf and. in time for Trixie, but i'm swamped and working on
MPI transition(s) and gcc14 FTBFS bugs.
So functionality changes in dh-fortran-mod will be stalled; just bug
fixes to maintain the status quo until post-trixie.
I'll get back to you later on dh-fortran and a list.
regards
Alastair

Commander Vimes didn’t like the phrase “The innocent have nothing to fear,”
believing the innocent had everything to fear, mostly from the guilty but in
the longer term
even more from those who say things like “The innocent have nothing to fear.”
