[arm] Support building as a Linux userspace binary for AArch32

Add support for building as a Linux userspace binary for AArch32.
This allows the self-test suite to be more easily run for the 32-bit
ARM code.  For example:

  make CROSS=arm-linux-gnu- bin-arm32-linux/tests.linux

  qemu-arm -L /usr/arm-linux-gnu/sys-root/ \
           ./bin-arm32-linux/tests.linux
