[PATCH 1/3] Copy set_unbuffered_mode_saved.o on remote host

[Yao Qi <yao at codesourcery dot com>]

Hi,
When testing mingw32 native gdb on a remote host, I get the following
compile error:

i686-mingw32-gcc.exe break0.o break1.o  -w -g
/scratch/yqi/i686-pc-linux-gnu-lite-trunk/mingw32-gdb/gdb/testsuite/set_unbuffered_mode_saved.o
-lm  -o break
i686-mingw32-gcc.exe: error:
/scratch/yqi/i686-pc-linux-gnu-lite-trunk/mingw32-gdb/gdb/testsuite/set_unbuffered_mode_saved.o:
No such file or directory

the compilation is done on host, but we pass a file name with the
directory on build.  This patch fixes this problem by keeping the tail
name of set_unbuffered_mode_saved.o if host is remote.

With this patch applied, it becomes:

i686-mingw32-gcc.exe break0.o break1.o  -w -g  set_unbuffered_mode_saved.o -lm  -o break

gdb/testsuite:

2013-07-10  Yao Qi  <yao@codesourcery.com>

	* lib/gdb.exp (gdb_compile): Set
	gdb_saved_set_unbuffered_mode_obj to
	set_unbuffered_mode_saved.o if host is remote.  Invoke
	remote_download to copy $unbuf_obj to host.
