There is no file of that name on the machine; but we'll be using
TCG anyway because /dev/kvm is not readable by my user.

It's the gcc compile farm ppc64 box (gcc110 if you have compile farm
access):
Linux gcc1-power7.osuosl.org 3.10.0-514.26.2.el7.ppc64 #1 SMP Mon Jul
10 02:26:53 GMT 2017 ppc64 ppc64 ppc64 GNU/Linux
/proc/cpuinfo says
processor : 0
cpu : POWER7 (architected), altivec supported
clock : 3550.000000MHz
revision : 2.1 (pvr 003f 0201)
[etc]
timebase : 512000000
platform : pSeries
model : IBM,8231-E2B
machine : CHRP IBM,8231-E2B
git bisect blames "target/ppc: 'PVR != host PVR' in KVM_SET_SREGS workaround"
for the regression.
