Well, as long as we are on the subject of gld, I have a question:
I am trying to put a NetBSD ident section in the kernel. The code
is #ifdef notyet in /usr/src/sys/conf/newvers.sh because I don't
know how to convince the linker to work. When I enable it, the
linker prints:

    ld: netbsd: Not enough room for program headers (allocated 3, need 4)
    ld: final link failed: Bad value

This is because the ident section is:

__asm(
        ".section\t\".note.netbsd.ident\", \"a\"\n"
        "\t.p2align\t2\n"
        "\t.long\t" _S(ELF_NOTE_NETBSD_NAMESZ) "\n"
        "\t.long\t" _S(ELF_NOTE_NETBSD_DESCSZ) "\n"
        "\t.long\t" _S(ELF_NOTE_TYPE_NETBSD_TAG) "\n"
        "\t.ascii\t" _S(ELF_NOTE_NETBSD_NAME) "\n"
        "\t.long\t" _S(__NetBSD_Version__) "\n"
        "\t.p2align\t2\n"
);

And this ident section causes another program header to be allocated?!?
How do I fix this?
