4Subject: [PATCH] configure: Use CFLAGS and LDFLAGS when doing link tests
5
6Some case link flags contain important flags which are required during
7linking, link fails otherwise without them, which can result in
8configure detection go wrong, ensure these flags are used along with CC
9when tests involve linking
