linux32 1-3build1 (amd64 binary) in ubuntu gutsy

 the linux32 tools allows 64bit systems with support for 32 bit
 applications to set the personality to the 32 bit native type.
 .
 For instance, on an amd64 or ia64 machine, commands run with this
 wrapper will think the machine type is i686, as returned by uname -m.
 .
 On systems without support for the PER_LINUX_32 execution domain, this
 program has no effect.
