[PATCH] sim: erc32/m32c/rl78: add sim_memory_map stub for gdb

[Mike Frysinger via Gdb-patches <gdb-patches@sourceware.org>]

These ports don't use the common sim core, so they weren't providing
a sim_memory_map for gdb, so they failed to link with the new memory
map logic added for the sim.  Add stubs to fix.

erc32/
	* interf.c (sim_memory_map): Define.

m32c/
	* gdb-if.c (sim_memory_map): Define.

rl78/
	* gdb-if.c (sim_memory_map): Define.
