Robert Yang 016b91b334 bitbake: cooker: Cleanup the queue before call process.join()
Fixed:
$ rm -fr tmp-glibc/cache/default-glibc/qemux86/x86_64/bb_cache.dat* ; bitbake -p
Press *one* Ctrl-C when the parsing process is at about 50%, then the processes
are not exited:

Keyboard Interrupt, closing down...

Timeout while waiting for a reply from the bitbake server

It hangs at process.join(), according to:

https://docs.python.org/3.7/library/multiprocessing.html

Cleanup the queue before call process.join() can fix the problem.

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.
