* Makefile.in: Bump to version 1.92.

	* Makefile.in:  Bump to version 1.92.
	* version.c, Makefile.in:  Get version string from Makefile.
	* copy.c, is-strip.c, not-strip.c, maybe-strip.c, Makefile.in:
	Make the same change that we earlier did for ar/ranlib:
	Generate two different binaries for strip and copy and use
	a global variable with different values to distinguish
	ostrip from copy.  (-1 means to use argv[0] to decide,
	so you can get the old behavior, but it is no longer the default).
	* copy.c (copy_file):  Set EXEC_P of output bfd if input is so.
	* copy.c (main):  If is_strip==-1, compare last 5 chars
	of argv[0], not the whole path.
	* copy.c (main): Return 0, not 1.
	* copy.c (setup_sections):  Fix due to change in bfd_make_section
	now failing if asked for a duplicate section.
	* strip.c, ostrip.c:  Removed obsolete files.
	* ar.c, not-ranlib.c, maybe-ranlib.c:
	Change encoding of is_ranlib variable to be consistent
	with is_strip for strip.copy (i.e -1 to means use argv[0]).
