examples: select libgcc for non-default architecture

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.
