Subject: [PATCH] Don't build libtcc1 with -fstack-protector-strong

Prevent libtcc1.a to be compiled with -fstack-protector-strong, so that
linking with tcc doesn't fail because symbol '__stack_chk_fail_local' is
not present in libtcc1.a. This is useful only if the CFLAGS passed from
the main Makefile contain this flag.
