[PATCH] sim: common: fix printf formats

[PATCH] sim: common: fix printf formats

[Mike Frysinger]

For 32-bit targets, %x happens to work for unsigned_word.  But for
64-bit targets, it's too small, and gcc throws an error.  Use the
right printf format define for them.

* sim-core.c (sim_memory_map): Change %#x to PRIxTW.

Missing ChangeLog, otherwise, LGTM.
