+Subject: [PATCH] don't pick up bundled db from host rpm
+
+For libsolv-native with rpm v4 in openembedded but on a host with
+existing /usr/include/rpm/db.h the build is configured to have
+HAVE_RPM_DB_H because of the existing header file from the host,
+but linking against the librpm.so in recipe-sysroot-native fails.
+
+Skip the check for rpm/db.h and assume that rpm is provided without
+a bundled berkley db.
+
+Fixes the following link errors:
+| ../ext/libsolvext.so.0: undefined reference to `db_create_rpmdb'
+| ../ext/libsolvext.so.0: undefined reference to `db_env_create_rpmdb'
+
+Observed on a openSUSE Leap 42.1 build host with rpm-devel installed.
+
+Upstream-Status: Inappropriate [oe build specific]
