Subject: [PATCH] build: Add -Wno-typedef-redefinition to CFLAGS

Without the -Wno-typedef-redefinition option, clang complains if a typedef
gets redefined in gnu99 mode (since this is officially a C11 feature). This
also happened with old versions of GCC.

So, don't break the build on such warn, since we want to support
toolchains that supports C11 anyways.
