[Mesa-dev] [PATCH] configure: check for dladdr via AC_CHECK_FUNC/AC_CHECK_LIB

[Pali Rohár]

This problem happen when gcc is compiled with LTO support (even 
if is not used). Also in some manpage (I do not remember) is 
written that it depends on order of arguments for compiler/linker

Btw, you can add my Signed-off-by to commit message.
