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- Remove outdated hacks, i.e. for `ar`.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.
