[OE-core] Berkely-DB QA-Test: RPATH error in upon adding configure flag -- db_5.3.{15, 21}.bb

[Martin Zenzes]

Hi,

I'm using the poky/yocto build-system, which are based on 
opembedded-core. Building one of their "vanilla" images works, adding 
the "Berkely DB" without changing it's default settings compiles too. 
But the default-configuration of the Berkely DB is not using the c++ 
interface so:

Upon adding the "--enable-cxx" configure option to the db-recipe I get 
the following "RPATH" error message during the "do_package" stage:

WARNING: QA Issue: db: Files/directories were installed but not shipped
   /usr/lib/libdb_cxx.so
ERROR: QA Issue: package db contains bad RPATH

ERROR: QA run found fatal errors. Please consider fixing them.

Happens on the "db_5.3.15.bb" and the "db_5.3.21.bb" recipe as well. 
Overwriting the "do_package_qa()" function in the recipe hides the error...

Any pointers on how to succeed?
