[PATCH] TILEPro/BFD: Don't crash on discarded GOT

[Maciej W. Rozycki]

Hi,

 This change fixes a linker crash where GOT is produced but not copied to 
output, e.g. because of the .got.plt input section being discarded through 
the /DISCARD/ linker script keyword -- not a particularly useful use case, 
but the linker shouldn't crash regardless.

 OK to apply?

	* elf32-tilepro.c (tilepro_elf_finish_dynamic_sections): Don't set 
	GOT's entry size if there is no ELF section data.
