The full output of that failing command is:
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
/usr/bin/qemu-system-x86_64 -device ? -device pci-assign,? -device virtio-blk-pci,?
-device virtio-net-pci,? -device scsi-disk,?
KVM not supported for this target
No accelerator found!
Adding the option '-machine accel=kvm:tcg' fixes the output.
Sigh, qemu-kvm.git has done a broken merge yet again. Binaries built from
qemu.git work fine when /dev/kvm is missing & this shoud not be changed
by qemu-kvm.git I've previously fixed it with

Fix default accelerator when configured with --disable-kvm
The default accelerator is hardcoded to 'kvm'. This is a fine
default for qemu-kvm normally, but if the user built with
./configure --disable-kvm, then the resulting binaries will
not work by default
* vl.c: Default to 'tcg' unless CONFIG_KVM is defined
