Check symbol defined by assignment in linker script

Symbol symbol defined by an assignment in a linker script has type
bfd_link_hash_new.  elf_i386_convert_load and elf_x86_64_convert_load
should check bfd_link_hash_new to see if a symbol is defined by a linker
script.

bfd/

	PR ld/19175
	* elf32-i386.c (elf_i386_convert_load): Check bfd_link_hash_new
	instead of calling bfd_link_get_defined_symbol.
	* elf64-x86-64.c (elf_x86_64_convert_load): Likewise.  Skip
	relocation overflow for bfd_link_hash_new.
	* linker.c (bfd_link_get_defined_symbol): Removed.
	* bfd-in2.h: Regenerated.
