[PATCH] Do not use dummy bfd suffix for recognition, make it human-readable instead.
ld/ChangeLog:
2011-03-10 Dave Korn <dave.korn.cygwin@gmail.com>
* plugin.c (IRONLY_SUFFIX): Revise to nicely human-readable form.
(IRONLY_SUFFIX_LEN): Delete.
(plugin_get_ir_dummy_bfd): Don't append IRONLY_SUFFIX.
(is_ir_dummy_bfd): Don't look for suffix; check claimed flag of
enclosing lang input statement instead.
