Plugin target handling
This patch fixes failures with LTO on mingw32 targets. Since git commit 7cf7fcc83c all possible targets (minus binary) are matched in bfd_check_format_matches rather than lower priority targets being excluded once a higher priority target matches. During linking that results in the ld/plugin.c plugin_object_p function being called with the input file xvec set to plugin_vec, which means plugin_get_ir_dummy_bfd doesn't see the real format of the file (pe-i386). It defaults to the output format instead, which happens to be pei-i386, and this wrong choice persists for the dummy bfd. pei-i386 isn't recognised as a valid linker input file. So, omit recognizing a plugin object in bfd_check_format_matches when some other object format matches, and make sure those other object formats are checked first. * format.c (bfd_check_format_matches): Don't match plugin target if another target matches. Expand comment. * targets.c (_bfd_target_vector): Move plugin_vec after all other non-corefile targets, outside !SELECT_VECS. * config.bfd: Don't handle targ=plugin here. * configure.ac: Don't add plugin to enable_targets or handle in target loop setting selvecs and other target vars. * configure: Regenerate.
