Subject: gdb-rhbz1553086-binutils-warning-loadable-section-outside-elf.patch

;; Fix 'gdb: warning: Loadable section ".note.gnu.property" outside of
;; ELF segments' (Nick Clifton, RH BZ 1553086).
;; This is a binutils patch.

Stop the BFD library from issuing a warning message when processing allocated sections in debuginfo files that lie outside of any loadable segment.

	PR 24717
	* elf.c (is_debuginfo_file): New function.
	(assign_file_positions_for_non_load_sections): Do not warn about
	allocated sections outside of loadable segments if they are found
	in a debuginfo file.
	* elf-bfd.h (is_debuginfo_file): Prototype.
