Properly check symbol defined by assignment in linker script
Symbol defined by a linker assignment may have type bfd_link_hash_new
or bfd_link_hash_undefined. And h->def_regular is always set.
elf_i386_convert_load and elf_x86_64_convert_load should check
h->def_regular as well as bfd_link_hash_undefined and bfd_link_hash_new
to see if a symbol is defined by a linker script.

* elf32-i386.c (elf_i386_convert_load): Check h->def_regular
instead of bfd_link_hash_new.
* elf64-x86-64.c (elf_x86_64_convert_load): Likewise. Skip
relocation overflow for bfd_link_hash_undefined and
bfd_link_hash_new if h->def_regular is set.
