Details:

In the Unix port, both the minimal project (echop) and simhot provide a
--debug option. This option works on simhost but has no effect on echop.

On both projects, the option sets a global variable debug_flags which,
according to the comments, is exported in lwipopts.h. The comment is
correct in simhot, where lwipopts.h contains

    extern unsigned char debug_flags;
    #define LWIP_DBG_TYPES_ON debug_flags

but the variable is not exported in echop.

The attached patch fixes the issue by copying the relevant lines from
unixsim/lwipopts.h into minimal/lwipopts.h.
