From ab5df4826c4a532da78828b72a2751c899e27ef2 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Tue, 8 Mar 2022 22:31:21 -0800
Subject: [PATCH] configure: Use CFLAGS and LDFLAGS when doing link tests
Some case link flags contain important flags which are required during
linking, link fails otherwise without them, which can result in
configure detection go wrong, ensure these flags are used along with CC
when tests involve linking
