LoongArch: Add support for OUTPUT_FORMAT("binary")
In binary output format, loongarch_elf_hash_table return NULL and result
in segment fault.
When ld output binary file, it seems that elf related functions should
not be called. But loongarch_elf_relax_section be called and
loongarch_elf_hash_table cause segment fault.
Just redefined loongarch_elf_hash_table and always return
link_info->hash.
The tests of binutils, glibc and gcc is ok.
