Richard,

I tried to use the PACKAGECONFIG_append_class-target but in that case opkg is build
without pgpme and signing enabled. Note: I wish to be able sign packages on the build machine and verify
the signatures on the board. Both using PGP.

Then I also tried to add 'native' to the gpme_1.4.3.bb recipe, but the build failed. Obviously other
changes are required for that to work.

Finally I tried to apply the patches described here:
https://www.mail-archive.com/openembedded-core@lists.openembedded.org/msg55204.html

But the build fails:

ERROR: Nothing RPROVIDES 'gnupg-native' (but virtual:native:/media/datadisk/arm/fsl-
community-bsp-daisy/sources/poky/meta/recipes-devtools/opkg/opkg_0.2.1.bb RDEPENDS on or otherwise requires it)
NOTE: Runtime target 'gnupg-native' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['gnupg-native']
ERROR: Required build target 'my-image' has no buildable providers.
Missing or unbuildable dependency chain was: ['my-image', 'opkg-native', 'gnupg-native']

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

Thanks and regards,
Lars
