Just to clear up a bit of confusion, packaging (e.g. the -dev package) has 
nothing to do with populating files into the sysroot, other than that files 
for each are originally pulled from the same location (i.e. files that get 
installed into ${D} during do_install). So the determining factors for a file 
going into the sysroot are (a) it has been installed into ${D} during 
do_install and (b) it has been installed under one of a list of specific paths 
as controlled by SYSROOT_DIRS.
