[php-src] Issue #12082: Invalid library on macOS when compiling libphp statically

Issue: https://github.com/php/php-src/issues/12082 Author: dunglas ### 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. 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 libtoo, 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
