--- Comment #4 from Emil Velikov <emil.l.velikov at gmail.com> ---
-dl is (module bugs of course) already passed then libGL/libGLX_mesa is build.

As pointed out we don't have a libtool which honours fsanitize, so I'd suggest
adding it to the CC/CXX variables like below.

./autogen.sh CC="gcc -fsanitize=address" CXX="g++ -fsanitize=address"

Note: I'm wondering if the explicit -lasan isn't agcc/clang bug. Can we get a
reference reading why we need it, considering the explicit -f.... toggle we
pass to gcc/clang.
