        the hello32 test is always installed and run on systems that may
        support "cc -m32" args, but not have installed libs (MKCOMAPT=no.)

        martin and i discussed splitting it up into a separate case that
        can be installed or not based upon make variables, which would allow
        non-bogus failures for these systems.  we also discusssed a few other
        ideas, and he asked me to file this PR with info.

        in these lists, "MLIBDIR" is the /usr/lib/$MLIBDIR the compat libs
        are installed into.

        for amd64 we have:
                MLIBDIR=                i386
                LD+=                    -m elf_i386
                COPTS+=                 -m32
                CPUFLAGS+=              -m32
                LDADD+=                 -m32
                LDFLAGS+=               -m32
                MKDEPFLAGS+=            -m32

        for sparc64 we have:
                MLIBDIR=                sparc
                LD+=                    -m elf32_sparc
                COPTS+=                 -m32
                CPUFLAGS+=              -m32
                LDADD+=                 -m32
                LDFLAGS+=               -m32
                MKDEPFLAGS+=            -m32

        for mips64/64 we have:
                MLIBDIR=        64
            for BE:
                LD+=            -m elf64btsmip
            for LE:
                LD+=            -m elf64ltsmip
                COPTS+=         -mabi=64
                CPUFLAGS+=      -mabi=64
                LDADD+=         -mabi=64
                LDFLAGS+=       -mabi=64
                MKDEPFLAGS+=    -mabi=64

        for mips64/o32 we have:
                MLIBDIR=        o32
            for BE:
                LD+=            -m elf32btsmip
            for LE:
                LD+=            -m elf32ltsmip
                COPTS+=         -mabi=32 -march=mips3
                CPUFLAGS+=      -mabi=32 -march=mips3
                LDADD+=         -mabi=32 -march=mips3
                LDFLAGS+=       -mabi=32 -march=mips3
                MKDEPFLAGS+=    -mabi=32 -march=mips3
