You also need these switches, I think:
select I8259
select ISA_BUS
select SERIAL_ISA
select MC146818RTC
(ideally, it should be possible to disable all the other machines in
default-configs/i386-softmmu.mak and only compile with CONFIG_MICROVM=y
... but seems like there are also some other indirect dependencies left)
