    Subject[PATCH v4 mips-next 4/7] MIPS: vmlinux.lds.S: catch bad .rel.dyn at link time
    Catch any symbols placed in .rel.dyn and check for these sections
    to be zero-sized at link time.
    Eliminates following ld warning:

    mips-alpine-linux-musl-ld: warning: orphan section `.rel.dyn'
    from `init/main.o' being placed in section `.rel.dyn'

    Adopted from x86/kernel/vmlinux.lds.S.
