Maybe to add to 'can it be fixed?'
As I said, IMHO it is not broken, but
yes, one could pass an additional parameter to the compiler '-nostdinc'.
CHECK_INCLUDE_FILE(rpm/db.h HAVE_RPM_DB_H, "-nostdinc")
But this would break the intention of the test on the not '-native'
build as there
the rpm headers whould actually be found in the standard include directories.
So if OE ever would decide to change the rpm recipe to have an included db
this would not be picked up by the test in the not '-native' tests.
