Summary: compiling problem with "tcg_ctx"
Initial Comment:
When compiling kvm using the "--disable-cpu-emulation" flag on a 64 bit Intel
Ubuntu, the compiler aborts with error "undefined reference to tcg_ctx",
This problem exists since kvm-70.

This seems to work with kvm-74. The patch allowed compilation, and the
guest appears to be running well.

I'm not sure if this will make qemu work properly, but it fixes the build
(also attached). Can you confirm if this works?

KVM: QEMU: Fix userspace build with --disable-cpu-emulation
I'm not sure this will work properly, but fixes the build.
ppc might need something like this as well
