ack.  This causes also problems with populate_sdk as it can add
conflicting packages to the package set.  E.g. when having 'dropbear'
and 'openssh-sftp-server' in the image, the -dev RDEPENDS tries to add
the conflicting 'dropbear' and 'openssh' packages to the sdk.

Instead of (or better: additional to) changing 'RDEPENDS_${PN}-dev', I
would prefer the removal of 'ALLOW_EMPTY_${PN}-dev' from bitbake.conf.
There is not reason to create -dev packages for applications.

In 'meta/conf/bitbake.conf' the '${PN}' in

|:RDEPENDS_${PN}-dev = "${PN} (= ${EXTENDPKGV})"

should be replaced by something which means the "library" package(s).
