Solaris 64-bit also has ABI-separated library directories:

  Solaris x86:
    $ isainfo
    amd64 i386
    $ isainfo -v
    64-bit amd64 applications
            sse2 sse fxsr amd_3dnowx amd_3dnow amd_mmx mmx cmov amd_sysc cx8 tsc
            fpu
    32-bit i386 applications
            sse2 sse fxsr amd_3dnowx amd_3dnow amd_mmx mmx cmov amd_sysc cx8 tsc
            fpu
    $ isainfo -n
    amd64
    $ ls -ld /usr/lib/{32,64,amd64,i386}
    /usr/lib/i386: No such file or directory
    lrwxrwxrwx   1 root     root           1 May  4  2005 /usr/lib/32 -> ./
    lrwxrwxrwx   1 root     root           5 May  4  2005 /usr/lib/64 -> amd64/
    drwxr-xr-x  11 root     bin        13312 Dec  1 04:24 /usr/lib/amd64/

  Solaris sparc:
    $ isainfo
    sparcv9 sparc
    $ isainfo -v
    64-bit sparcv9 applications
            vis
    32-bit sparc applications
            vis v8plus div32 mul32
    $ isainfo -n
    sparcv9
    $ ls -ld /usr/lib/{32,64,sparcv9,sparc}
    /usr/lib/sparc: No such file or directory
    lrwxrwxrwx   1 root     root           1 Sep 11 14:48 /usr/lib/32 -> ./
    lrwxrwxrwx   1 root     root           7 Sep 11 14:48 /usr/lib/64 ->

    drwxr-xr-x  11 root     bin        13312 Sep 11 16:04 /usr/lib/sparcv9/
