[arm-gnu] interlinking with other EABI toolchains

[Nick Clifton]

Hi Kevin,

Although the cause of this problem has now been found (the TI assembler 
was emitting WEAK symbols in the LOCAL section of the symbol table) this 
does not excuse the linker - it should never seg fault.  Instead it 
should issue a proper error message and exit without completing the link.

Hence I am going to apply the patch below to fix this fault.  With the 
patch applied I now get:

   ld: error: bspSystem.o contains a reloc (0x00000602) for section 
.data that references a non-existent global symbol
   ld: final link failed: Bad value

when attempting to link your test case.

Daniel - I  would like this patch to go into the 2.16 branch if there is 
still time ?

Cheers
   Nick

	* elflink.c (elf_link_input_bfd): Handle the case where a badly
	formatted input file results in a reloc which has no associated
	global symbol.
