	if veneer already has an offset.
	(elf32_arm_create_stub): Return the stub entry pointer or NULL instead
	of a boolean indicating success or failure.
	(cmse_scan): Change stub_changed parameter into an integer pointer
	parameter cmse_stub_created to count the number of stub created and

	of return value in elf32_arm_create_stub.  Use
	arm_stub_section_start_offset () if not NULL to initialize size of
	secure gateway veneers section.  Initialize stub_offset of Cortex-A8
	erratum fix to -1.  Use ret to hold return value.
	(elf32_arm_build_stubs): Use arm_stub_section_start_offset () if not
	NULL to initialize size of secure gateway veneers section.  Adapt
	comment to stress the importance of zeroing veneer section content.
