Fixes the generation of dwarf line debug information for the msp430, even in the presence of function sections and linker garbage collection.
	PR 17940
	* dwarf2dbg.c (out_header): When generating dwarf sections use
	real symbols not temps for the start and end symbols.
	* config/tc-msp430.h (TC_FORCE_RELOCATION_SUB_SAME): Also prevent
	adjustments to relocations in debug sections.
	(TC_LINKRELAX_FIXUP): Likewise.

	* elf32-msp430.c (msp430_elf_relax_delete_bytes): Adjust debug
	symbols at end of sections.  Adjust function sizes.
