Bug 12721

Originally seen in our custom BSP with 'rocko' meta-* layers and bitbake '1.36'
Reproduced in poky branches pyro, rocko, sumo.
Worked fine in poky branch morty.

Issue seen with bitbake of any image (core-image-minimal, core-image-sato, etc), when you add the following to local.conf:

USERADD_ERROR_DYNAMIC = "error"
USERADDEXTENSION = "useradd-staticids"
USERADD_UID_TABLES = "./passwd"
USERADD_GID_TABLES = "./group"

Per Yocto manual  https://www.yoctoproject.org/docs/current/ref-manual/ref-manual.html#var-USERADD_ERROR_DYNAMIC

With or without the files 'group' and 'passwd' actually existing, bitbake will fail to parse random recipes - on poky usually 'dbus' fails, on our custom BSP & custom layers I see failures on seemingly-random recipe names.  

If you change the 
  USERADD_ERROR_DYNAMIC = "error"
to
  USERADD_ERROR_DYNAMIC = "warn"
then bitbake correctly parses recipes and correctly throws warnings about missing userIds and groupIds in the passwd/group files.

But with 
  USERADD_ERROR_DYNAMIC = "error"
bitbake fails to parse recipes.  Eg:

[tso_bldadm@AD.KEYSIGHT.COM@es-hpp-linux-build3 build.pyro]$ bitbake core-image-minimal
