First the good news. With --disable-tcg on my AArch64 system I can
successfully run:

  make vm-boot-ssh-ubuntu.aarch64 QEMU_LOCAL=1

and get a shell on a KVM powered VM. Bravo ;-)

Also I did a number of different builds:

   fdfind -0 -t x qemu-system-aarch64 | xargs -0 ls -lh
  -rwxrwxr-x 1 alex alex 129M Mar 23 18:09 all/qemu-system-aarch64
  -rwxrwxr-x 1 alex alex  64M Mar 23 18:16 disable.all/qemu-system-aarch64
  -rwxrwxr-x 1 alex alex  81M Mar 23 18:20 disable.defaults/qemu-system-aarch64
  -rwxrwxr-x 1 alex alex  94M Mar 23 18:12 disable.tcg/qemu-system-aarch64

Where the builds are:

  fdfind -0 -t f config.log | xargs -0 head -n 2
  ==> all/config.log <==
  # QEMU configure log Tue 23 Mar 2021 06:08:19 PM UTC
  # Configured with: '../../configure' '--skip-meson'

  ==> disable.all/config.log <==
  # QEMU configure log Tue 23 Mar 2021 06:15:26 PM UTC
  # Configured with: '../../configure' '--disable-docs' '--disable-tcg' '--without-default-features' '--without-default-devices'

  ==> disable.defaults/config.log <==
  # QEMU configure log Tue 23 Mar 2021 06:19:05 PM UTC
  # Configured with: '../../configure' '--disable-docs' '--disable-tcg' '--without-default-features'

  ==> disable.tcg/config.log <==
  # QEMU configure log Tue 23 Mar 2021 06:10:38 PM UTC
  # Configured with: '../../configure' '--disable-docs' '--disable-tcg'

And they all build OK and at least give a minimally viable binary. The
--without-default-devices build fails to boot a VM although that's
probably to be expected as we don't have any handling yet for a custom
device set (probably -M virt and the virtio devices in this case).
Unsurprisingly this gets the shortest distance in make check:

  Running test qtest-aarch64/qom-test
  qemu-system-aarch64: Unsupported NIC model: virtio-net-pci
  Broken pipe
  ERROR qtest-aarch64/qom-test - too few tests run (expected 1, got 0)
  make: *** [Makefile.mtest:24: run-test-1] Error 1

However I see other more esoteric failures in the other builds.
disable.tcg/disable.defaults:

  Running test qtest-aarch64/cdrom-test
  **
  ERROR:../../qom/object.c:714:object_new_with_type: assertion failed: (type != NULL)
  ERROR qtest-aarch64/cdrom-test - Bail out! ERROR:../../qom/object.c:714:object_new_with_type: assertion failed: (type != NULL)
  Broken pipe
  make: *** [Makefile.mtest:832: run-test-102] Error 1

As well as a failure on the normal build:

  Running test qtest-aarch64/migration-test
  ERROR qtest-aarch64/migration-test - Bail out! ERROR:../../target/arm/tcg/tcg-cpu.c:233:tcg_arm_init_accel_cpu: assertion failed: (object_class_by_name(ACCEL_CPU_NAME("tcg")
  ) == OBJECT_CLASS(accel_cpu))
  Broken pipe
  make: *** [Makefile.mtest:272: run-test-32] Error 1

I'll see if I can do some bisecting to find the culprits.

Yeah this is basically --without-default-devices with a KVM only subset
of devices.
