IA32_BINARY_PORT checks /usr/lib32 and compat.ia32.maxvmem presence.
I don't think it'll work with dynmaic linking against 32bit library
from ports (not misc/compat[3-7]x).

As there is currently only 32bit linux base support I think only
compat.linux32.maxvmem needs to be checked for USE_LINUX case.
