The initial reason is that after the merger of 29fe5067ed07
("kexec: make -a the default"), kexec cannot be used on LoongArch,
MIPS .etc architectures. We need to add "-c" for normal use. The
current kexec_file_load system call is not implemented in
architectures such as LoongArch, so it needs to pass kexec_load.
So we need to set __NR_kexec_file_load to undefined in unsupported
architectures. This will return EFALLBACK via is_kexec_file_load_implemented,
and then via kexec_load.
