Richard Purdie bcdafed2db useradd: Fix build architecture corruption of sstate artefacts
When mixing aarch64 and x86_64 host builds with common sstate, useradd failures
were found. This was due to references to:

/home/pokybuild/yocto-worker/qemuarm/build/build/tmp/sysroots-components/aarch64/pseudo-native/usr/bin/pseudo
or
/home/pokybuild/yocto-worker/qemuarm/build/build/tmp/sysroots-components/x86_64/pseudo-native/usr/bin/pseudo

on the wrong architecture within the useradd postinst files.

Instead of using COMPONENTS_DIR as the FIXME, use PSEUDO_SYSROOT which contains
the arch component as well to avoid this.

Add extra comments to cause the relavent sstate to be rebuilt.

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.
