Our libtool patch does not apply due to the shipped file being patched
upstream:
https://gitweb.git.savannah.gnu.org/gitweb/?p=libiconv.git;a=commitdiff;h=2f2b617f0334cd8b4313bcd84ce6a49713a7d848
* build-aux/ltmain.sh: Update from libtool-2.5.4, with modifications:
2017-07-15 Bruno Haible <bruno@clisp.org>
Allow building statically linked binaries, through
LDFLAGS="-static". Apply patch from
<https://lists.gnu.org/archive/html/bug-libtool/2017-07/msg00000.html>.
* build-aux/ltmain.sh (func_mode_help, func_mode_link): In the
link mode, accept option '-static-uninstalled-libs' in place of
'-static', and make '-static' an equivalent of '-all-static'.
* libcharset/build-aux/ltmain.sh: Likewise.
Added 0001-libtool.patch as rebased version of
