* configure.ac (build_lto_plugin): New shell variable.
(--enable-lto): Turn on by default for all non-ELF platforms that have had LTO support added so far. Set build_lto_plugin appropriately for both ELF and non-ELF. (configdirs): Add lto-plugin or not based on build_lto_plugin. * configure: Regenerate.
