I just did a quick test of bitbake 2.8 in ISAR and that (almost) worked
out of the box. Only required change was to move the
kbuildtarget.bbclass into the meta/classes dir.

Probably the only relevant changes are around the handling of PR:

- The PR value can no longer be set from the recipe file name - this
was rarely used, but in any case is no longer supported.
- PE and PR are no longer included in the work directory path
(WORKDIR). This may break some tool assumptions about directory paths,
but those should really be querying paths from the build system (or not
poking into WORKDIR externally).
