qemu-softmmu -cpu help broken

[Max Filippov]

Hello,

I've noticed that the command
 qemu-system-xtensa -cpu help
no longer prints anything. Apparently because cpu_list is no longer defined
in list_cpus inside softmmu/cpus.c

Bisection points to the following commit:
e0220bb5b200 ("softmmu: Build target-agnostic objects once")

Reverting the change for the cpus.c fixes it for me:

I can send a proper patch if this is the right fix, please
let me know.
