Hi libtool dev,
We've recently hit an issue cross-compiling some package using libtool
for sysroot. Saying libfoo.la contains
libdir=/usr/lib
Then libtool will add "-L/usr/lib" to the linker command line during a
"relink" against libfoo.la, because ltmain.in:6500:
> else
> # We cannot seem to hardcode it, guess we'll fake it.
> add_dir=-L$libdir
^^^^^^^^^
> # Try looking first in the location we're being installed to.

Now the linker will try to use the system library in /usr/lib, causing
link error or runtime issue.
There is a patch at
https://lists.gnu.org/archive/html/libtool-patches/2021-10/msg00017.html
changing -L$libdir to -L$lt_sysroot$libdir at this line, but maybe the
author didn't submitted it properly (I guess it should be submitted into
https://savannah.gnu.org/patch/?group=libtool, instead of the list).
Could this change, or something similar be applied in the incoming new
release?
