As far as I am aware, this is intentional.  For various SDK items 
pseudo/libpseudo may be used.  On a 32-bit SDK, only a 32-bit pseudo/libpseudo 
is available.  This will prevent it from working with any host system binaries 
that are x86_64.

If you don't care, the "workaround" is to use setarch and install it by telling 
the system you are an ix86 target.
