Ryan Rowe 2c7dcad9b7 python3: fix PGO for non-reproducible biniaries
When PGO was disabled by default by e53ebf29, a bug was introduced that
prevented PGO from ever being enabled. At the time at which extra config
is appended to PACKAGECONFIG_CONFARGS, PACKAGECONFIG_PGO remains
unevaluated in PACKAGECONFIG_class-target, due to setting its value in
an anonymous Python function. As a result, the PGO options options will
never be included.

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.
