Richard Purdie de6f1393e9 scripts/oe-build-perf-report: Avoid buildstats warning
When a comparision branch is set we see warnings. If two branches are used,
look for buildstats information from both to avoid this kind of warning:

INFO: Parsing buildstats from 'refs/notes/buildstats/perf-centos7.yoctoproject.org/master-next/qemux86'
WARNING: Buildstats not found for perf-centos7.yoctoproject.org/master/qemux86/56808-g08220028e52992dcba667fc97bf3afe8be1949fb/0
WARNING: Buildstats not found for perf-centos7.yoctoproject.org/master/qemux86/56808-g08220028e52992dcba667fc97bf3afe8be1949fb/1
INFO: Buildstats were missing for some test runs, please run 'git fetch origin refs/notes/buildstats/perf-centos7.yoctoproject.org/master-next/qemux86:refs/notes/buildstats/perf-centos7.yoctoproject.org/master-next/qemux86' and try again

(the warning is due to stats being looked for in both branches, choose
the other branch and different warnings would be shown)

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
