Thanks for the patch.  I haven't been able to test it yet, but looking
through it, it appears that the 'use case' is:

on $build, when building a libtoolized project, you configure as:

path/to/configure --build=$build --host=$host \
        --prefix=$sysroot_of_compiler$prefix_for_host \
        ...

and then compile and install as usual (somehow arranging that -sysroot
is passed to libtool, whenever appropriate).  Is that correct?


The reason I ask, is it sure would be nice if one could instead do this:

path/to/configure --build=$build --host=$host \
        --prefix=$prefix_for_host \
        ...

and the compile as usual -- but when installing, do

make install prefix=$sysroot_of_compiler$prefix_for_host

(again, somehow arranging for libtool to get the -sysroot option).

This way, there is little danger that the value of $sysroot_of_compiler
would get hardcoded into any of the binaries, especially as they may one
day be deployed to $host where they will live in $prefix_for_host,
without a $sysroot_of_compiler in sight.

Or am I misunderstanding something?
