Add support for locating separate debug info files via the build-id method.
PR binutils/20876 bfd * opncls.c (find_separate_debug_file): Add include_dirs parameter. Only include the directory part of the bfd's filename in search paths if include_dirs is true. Add a couple of extra locations for looking for debug files. ( bfd_follow_gnu_debuglink): Update invocation of find_separate_debug_file. (bfd_follow_gnu_debugaltlink): Likewise. (get_build_id): New function: Finds the build-id of the given bfd. (get_build_id_name): New function: Computes the name of the separate debug info file for a bfd, based upon its build-id. (check_build_id_file): New function: Checks to see if a separate debug info file exists at the given location, and that its build-id matches that of the original bfd. (bfd_follow_build_id_debuglink): New function: Finds a separate debug info file for a given bfd by using the build-id method. * dwarf2.c (_bfd_dwarf2_slurp_debug_info): Try using the build-id method of locating a separate debug info file before using the debuglink method. * bfd-in2.h: Regenerate. binutils * NEWS: Mention the new feature. * testsuite/binutils-all/objdump.exp (test_build_id_debuglink): New proc to test the location of separate debug info files using the build-id method.
