gdbserver/ChangeLog:

* Makefile.in (SFILES): Remove hostio-errno.cc.
* configure: Regenerate.
* configure.ac (GDBSERVER_DEPFILES): No longer add
$srv_hostio_err_objs.
* configure.srv (srv_hostio_err_objs): Delete.
* hostio-errno.cc: Delete.
* hostio.cc (hostio_error): Inline hostio_last_error_from_errno
here.
* hostio.h (hostio_last_error_from_errno): Delete.
* target.cc (process_stratum_target::hostio_last_error): Delete.
* target.h (class process_stratum_target) <hostio_last_error>:
Delete.
