From 36473395f1e7574fc22fd4f5210ad6a8def76d91 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 18 Jan 2012 11:27:24 -0800 Subject: autoconf: Fix build of dri symbols test to not manually link expat. AC_CHECK_LIB has this nasty behavior, like the cflags tests, of automatically putting the tested value into the global LIBS on success. This caused -lexpat to end up in LIBS, but without the --with-expat dir, so my 32-bit build on a 64 system using expat from a custom prefix could only find the system expat and fail to link on the one current consumer of the LIBS variable: the dri driver test link.
