PATCH COMMITTED: Output local section symbol relocs to merge sections

[Ian Lance Taylor]

This patch adds support for outputting relocs against local section
symbols defined in merge sections.  I originally thought this case
could not happen because I couldn't figure out any way to generate
code for it.  But then I did figure out how to generate it, if we
permit x86-64 non-PIC object files to go into shared libraries.  Which
we don't, but that's OK, the case will arise for other processors.

I committed this patch to make it work, including a test case which
would trigger it if we could.

	* output.cc (Output_reloc<SHT_REL>::local_section_offset): Add
	addend parameter.  Change caller.  Handle merge sections.
	(Output_reloc<SHT_REL>::symbol_value): Change parameter type from
	Address to Addend.  Don't add in the result of
	local_section_offset, pass down the addend and use the returned
	value.
	* output.h (class Output_reloc<SHT_REL>): Add Addend typedef.
	Update declarations of local_section_offset and symbol_value.
	* testsuite/two_file_test_1.cc (t18): New function.
	* testsuite/two_file_test_2.cc (f18): New function.
	* testsuite/two_file_test_main.cc (main): Call t18.
	* testsuite/two_file_test.h (t18, f18): Declare.
