[commit/obvious] Fix PR sim/16018

[Sergio Durigan Junior <sergiodj@redhat.com>]

Hi,

I have committed the following patch as an obvious fix for PR
sim/16018.  It just adds missing "break" statements in a switch.

I must confess that I did not manage to build ERC32 sim.  What I did
was:

  ../gdb-src/configure --target=sparc-rtems4.11 --enable-sim --enable-sim-hardware

And I received the following error:

  In file included from ../../../../../gdb-src/sim/erc32/../../include/gdb/callback.h:55:0,
                   from ../../../../../gdb-src/sim/erc32/sis.h:24,
                   from ../../../../../gdb-src/sim/erc32/exec.c:23:
  ../../bfd/bfd.h:1070:48: error: unknown type name ‘size_t’

Strange...  I did not investigate too much, but maybe I'm doing
something wrong.

Anyway, patch applied.
