When an LTO linker plugin claims an external member of a thin archive, gold does not properly unlock the file and make its file descriptor available for reuse. This patch fixes the problem by modifying Archive::include_member to unlock the object file via an RAII class instance, ensuring that it will be unlocked no matter what path is taken through the function. gold/ PR gold/15660 * archive.cc (Thin_archive_object_unlocker): New class.
