* gdbserver/Makefile.in: add dependency on XM_CLIBS.
* gdbserver/low-sim.c (registers) force into alignment.
(create_inferior): Fix typo on new_argv; add abfd arg to
sim_open, sim_create_inferior. Add reg_size arg to
sim_fetch_register, sim_store_register. Make simulator
take a single-step to get into a known running state.
* gdbserver/gdbreplay.c: include fcntl.h for def'n of F_SETFL.
* gdbserver/server.c: Add remote_debug variable to control
debug output.
* gdbserver/server.h: Add prototypes for enable/disable_async_io.
* gdbserver/remote-utils.c: add verbose debugging output controlled
by "remote_debug" variable. Add call to "disable_async_io()"
to avoid being killed by async SIGIO signals.
* config/m32r/m32r.mt: define GDBSERVER_(LIBS and DEPFILES),
so that gdbserver can be built with the m32r simulator.
