DRI2 detection could fail if configure is invoked with a sysroot passed as CFLAGS. Ideally configure should invoke gcc with the sysroot argument passed to the configure script, but for some reason this is not done by AC_COMPILE_IFELSE.
Fix this by ensuring CFLAGS are preserved when checking for stuff.
