Richard Purdie c37d0c4aa5 bitbake: siggen: Fix performance issue in get_unihash
There is a significant performance issue in get_unihash(). The issue turns out
to be the lookups of setscene tasks. We can fix this by using a set() instead of
the current list.

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.
