uClibc defines EM_OR1K instead of EM_OPENRISC for the OpenRISC ELF
e_machine ID. Use EM_OR1K when EM_OPENRISC is not defined.
This fixes the following build failure:
In file included from nlist.c:44:0:
nlist.c: In function ‘__elf_is_okay__’:
local-elf.h:224:23: error: ‘EM_OPENRISC’ undeclared (first use in this function)
