USE_N32 was dropped years ago. That leaves USE_X32 as the only special case. We cannot rely on the abi_x86_x32 USE flag here as we also need this for the build host. We were previously only doing this for the build host when cross-compiling, but it's now also needed for multilib. Now that the test is simpler, just do it unconditionally. Also call tc-export_build_env to populate BUILD_CFLAGS and BUILD_LDFLAGS from CFLAGS and LDFLAGS when appropriate.
