In theory a softmmu target is freestanding and does not need anything beyond the compiler install, so configure defaults to the native compiler, which is biarch. That however assumes that the compiler install includes the libgcc for both architectures. Does that mean that Ubuntu installs GCC without a 32-bit libgcc.a?
