Invalid library on macOS when compiling libphp statically

Description

When building PHP as a static library for macOS, the resulting libphp.a file cannot be linked and the following (weird) error occurs:

ld: warning: ignoring file /usr/local/lib/libphp.a, building for macOS-arm64 but attempting to link with file built for macOS-arm64

The problem only occurs if at least one extension depending on another static library has been compiled (ex: ext-curl, ext-sqlite3...). The linking is done correctly if it's not the case, or if there are dependencies to shared libraries.

Extracting the .o file from the archive and recreating it using ar also fixes the issue:

mkdir /tmp/php-o
cd /tmp/php-o
ar x /usr/local/lib/libphp.a
ar rcs /usr/local/lib/libphp.a *.o

I suspect that it's related to libtool, and specifically this line:

/bin/sh /Users/dunglas/workspace/static-php-cli/source/php-src/libtool --silent --preserve-dup-deps --tag CC --mode=link clang -static -fno-common -Wstrict-prototypes -Wall -Wextra

The problem can easily be reproduced using static-php-cli: https://github.com/crazywhalecc/static-php-cli/pull/153

PHP Version

PHP 8.2.9

Operating System

macOS 13.4.1 (M1)

在 macOS arm64 上使用 static-php-cli pull request 153 的设置重现该失败，然后检查报告中显示的 libtool 调用以及它如何创建 libphp.a。当包含 ext-curl 或 ext-sqlite3 等扩展的静态构建 libphp.a 无需提取并重新创建归档即可成功链接时，工作就完成了。
