[PATCH] Search .dwo in the binary directory.

[Ali Tamur via gdb-patches]

.dwo files generated by the compiler usually resides in the same directory as
the generated binary itself. Add that binary to the list of directories to
search when searching for the .dwo file.

gdb/ChangeLog:

	* dwarf2/read.c (try_open_dwop_file): Include binary directory to
	the list of directories to search.  Search the path also when looking
	for a .dwo file.
