The libtool 1.5.26 is bundled with PHP since the very early days of the
Autotools build system to ease the building process and avoid additional
dependency on the system Libtool. This updates the bundled libtool to
2.5.4 version.
Fixes and implementations:
- Fixed race conditions when building PHP in parallel ("cannot create
.libs" warnings).
- Implements request https://bugs.php.net/70374 (Update libtool.m4)
- Fixes libtool eating -flto flags.
- Fixes GH-17310 (configure producing errors on macOS)
- Fixes GH-15946 (./configure error when building with NixOS)
Changes:
- Add a script to update autotools files.
- libtool is spread across multiple files; phpize is updated to handle
this.
- Remove outdated hacks, i.e. for `ar`.
- Remove documentation references to external libtool, as we vendor it.
- `--with-pic` is now `--enable-pic`. Error out on the old flag.
- On macOS linker now uses -undefined dynamic_lookup flag for shared
extensions and shared embed SAPI (libphp) instead of older
'-undefined suppress -flat_namespace' combination.

This is addon to the GH-13727 bug fix. When configuring the build with:
./configure CFLAGS=-Werror=strict-prototypes
libtool check for parsing nm command would fail:
checking command to parse /usr/bin/nm -B output from cc object... failed
Upstream libtool has this specific check already fixed. Note that this
works only with Autoconf version 2.72 and later and is preparation for
future compilers that might have this error enabled by default.
autoconf/libtool generating code to test features missed `void` for
C calls prototypes w/o arguments.
Note that specific changes related to libtool have to be upstreamed.

C99 no longer has implicit function declarations and implicit ints.
Current GCC versions enable them as an extension, but this will
change in a future GCC version.
Simplest fix is to remove the specific checks for freebsd1* as it also matches freebsd10,
and nobody should be using >=PHP 5.4 with freebsd 1.x(if it is even possible to make it
to compile there).
