[php-src] Issue #8197: `OCIStmtFetch2 in -lclntsh...` check is always `no` on Alpine

Issue: https://github.com/php/php-src/issues/8197 Author: mvorisek ### Description see https://github.com/mlocati/docker-php-extension-installer/issues/523 the Oracle Instant Client is installed using https://github.com/mlocati/docker-php-extension-installer/blob/c14bd17033b7bc45c262c9bf48a6f26b9ba92bc1/install-php-extensions#L1913 and added to ldconf path in https://github.com/mlocati/docker-php-extension-installer/blob/c14bd17033b7bc45c262c9bf48a6f26b9ba92bc1/install-php-extensions#L1454 the problematic config.m4 check is done in https://github.com/php/php-src/blob/5b01c4863fe9e4bc2702b2bbf66d292d23001a18/ext/pdo_oci/config.m4#L178 it seems the Alpine ldconf patch in /etc/ld-musl-x86_64.path is completely ignored by PHP_CHECK_LIBRARY how to reproduce: 1. run clean & latest Docker Alpine image 2. download https://github.com/mlocati/docker-php-extension-installer/blob/master/install-php-extensions 3. run install-php-extensions pdo_oci 4. observe Oracle Instant Client is downloaded, instaled and php pdo_oci ext is configured & build, notice checking for OCIStmtFetch2 in -lclntsh... no check is always no (but yes on Debian image, with exactly the same steps) ### PHP Version any ### Operating System Alpine
