Remove process_stratum_target::hostio_last_error abstraction
Now that the WinCE port is gone, all ports map host I/O errors from errno, so this abstraction is no longer necessary. Basically undoes: https://sourceware.org/pipermail/gdb-patches/2008-January/055511.html https://sourceware.org/pipermail/gdb-patches/attachments/20080131/f44e7012/attachment.bin 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.
