[Qemu-devel] [PATCH] i386: fix '-cpu ?' output for host cpu type |

Since commit d6dcc5583e7, '-cpu ?' shows the description of the
X86_CPU_TYPE_NAME("max") for the host CPU model:
Enables all features supported by the accelerator in the current host
instead of the expected:
KVM processor with all supported host features
or
HVF processor with all supported host features
This is caused by the early use of kvm_enabled() and hvf_enabled() in
a class_init function. Since the accelerator isn't configured yet, both
helpers return false unconditionally.
A QEMU binary will only be compiled with one of these accelerators, not
both. The appropriate description can thus be decided at build time.
