Richard Purdie 58726c4a56 sstatesig: Optimise get_taskhash for hashequiv
With hashequiv the get_taskhash function is called much more regularly
and contains expensive operations. This these don't change based upon
hash in a given build, improve the caching within the function to
reduce overhead.

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.
