'boot-serial-test' does not work with a QEMU built with --disable-tcg in
a IBM POWER9 host. The reason is that without TCG QEMU will default to
KVM acceleration, but then the KVM module in IBM POWER hosts aren't able
to handle other CPUs.
The result is that the test will break with a KVM error when trying to
ruin the ppce500 test:
$ QTEST_QEMU_BINARY=./qemu-system-ppc64 ./tests/qtest/boot-serial-test
/ppc64/boot-serial/ppce500: qemu-system-ppc64: -accel tcg: invalid accelerator

Fix it by checking CONFIG_TCG before compiling boot-serial-test.
