[PATCH] Fix ld segfault with -Map -Tdata=xxx (arm-none-symbianelf, and maybe other targets)

Thanks for supplying this patch.  I am going to apply a variant of the 
patch (see attached) which allows the value for the symbol to be output 
into the map file even if its output section is not known.

Note - whilst looking into this bug I also found a place in elf32-arm.c 
which relied upon the symbol's section being present so I am including a 
fix for that as well.

You are correct however in thinking that there is something else that is 
deeply broken.  Specifying -Tdata (or -Ttext or -Tbss) should not be 
causing this behaviour.  I have looked into it for a while but I could 
find no obvious cause.  This will have to be something to come back to 
at a later date.

Cheers
   Nick

	* elf32-arm.c (elf32_arm_final_link_relocate): Gracefully handle
	the situation where a symbol's section is not known but a section
	relative R_ARM_RELATIVE reloc has to be generated for the Symbian
	OS.
