add libtool --mode=finish mode for sysroot

Browse Source 
* doc/libtool.texi (Finish mode): Document behavior when *.la files
are passed.
* libltdl/config/ltmain.m4sh (func_mode_finish): Eliminate sysroot
or `=' signs representing it from files in $libs.
* tests/sysroot.at (SYSROOT_TESTS): Test for presence of sysroot
references before running libtool --mode=finish, and for absence
afterwards.

@dfn{Finish} mode helps system administrators install libtool libraries
so that they can be located and linked into user programs.
@dfn{Finish} mode has two functions. One is to help system administrators
install libtool libraries so that they can be located and linked into
user programs. To invoke this functionality, pass the name of a library
directory as @var{mode-arg}. Running this command may require superuser
privileges, and the @option{--dry-run} option may be useful.
Each @var{mode-arg} is interpreted as the name of a library directory.
Running this command may require superuser privileges, so the
@option{--dry-run} option may be useful.
The second is to facilitate transferring libtool libraries to a native
compilation environment after they were built in a cross-compilation
environment. Cross-compilation environments may rely on recent libtool
features, and running libtool in finish mode will make it easier to
work with older versions of libtool. This task is performed whenever
the @var{mode-arg} is a @samp{.la} file.
