bug#24871: incorrect "cannot install XXX to a directory not ending in YY

I believe I've found a bug in libtool:

        $ libtool --tag=CC --mode=install install -D libfail.la 
/tmp/lib/libfail.la
        libtool:   error: error: cannot install 'libfail.la' to a directory not 
ending in /tmp/lib/

When the install directory clearly does end in the required string.

I belive that this is a duplicate of a previous message that was never resolved:
  http://lists.gnu.org/archive/html/bug-libtool/2009-12/msg00001.html

But, unlike the previous message, I have a minimal test case!

        # build the first library
        echo > pass.c
        libtool --tag=CC --mode=compile cc -c -o pass.lo pass.c
        libtool --tag=CC --mode=link    cc -o libpass.la -rpath /tmp/lib/ 
pass.lo
        
        # build a second library (that will fail to install)
        echo > fail.c
        libtool --tag=CC --mode=compile cc -c -o fail.lo fail.c
        libtool --tag=CC --mode=link    cc -o libfail.la -rpath /tmp/lib/ 
fail.lo libpass.la
        
        # try to install them
        libtool --tag=CC --mode=install install -D libpass.la 
/tmp/lib/libpass.la
        libtool --tag=CC --mode=install install -D libfail.la 
/tmp/lib/libfail.la

libpass will install fine, but libfail will fail to install, with the
error message I posted at the top.

I am using libtool 2.4.5 on an x86_64 GNU/Linux box (Parabola
GNU/Linux-libre; similar to Arch Linux):

        $ pacman -Q libtool
        libtool 2.4.6-6

        $ libtool --version
        libtool (GNU libtool) 2.4.6

The error occurs both with the system `libtool`, and
`./configure`-generated libtool.

I have not tried using libtool build from git.
