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.

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.
