In case of multilib-enabled toolchains if default architecture differ from the one examples are being built for linker will fail to link example object files with libgcc of another (non-compatible) architecture.

Interesting enough for years in main Makefile we used CFLAGS/c_flags for this but not for examples.

So fixing it now.
