[OE-core] Using package specific DESCRIPTION with do_split_packages

[Peter Urbanec]

Hi,

I've been wrestling with do_split_packages and package_ipk trying to 
generate packages that have a customised DESCRIPTION override. I could 
not get it to work. Here is roughly what I tried:

--- mytest.bb start ---
SUMMARY = "Generic summary"
DESCRIPTION = "Generic description"
...
DESCRIPTION_mytest-plugin-item1 = "Description specific to item1"
DESCRIPTION_mytest-plugin-item2 = "Description specific to item2"
...
RDEPENDS_mytest-plugin-item1 = "python-requests"
...
python populate_packages_prepend() {
     mytest_plugindir = bb.data.expand('${libdir}/mytest/Plugins', d)
     do_split_packages(d, mytest_plugindir, 
'^(\w+/\w+)/[a-zA-Z0-9_]+.*$', 'mytest-plugin-%s', 
'${DESCRIPTION_mytest-plugin-%s}', recursive=True, match_path=True, 
prepend=True)
     do_split_packages(d, mytest_plugindir, '^(\w+/\w+)/.*\.py$', 
'mytest-plugin-%s-src', '%s (source files)', recursive=True, 
match_path=True, prepend=True)
}

--- mytest.bb end ---

The .ipk files generated using do_split_packages always have the generic 
description and summary, instead of using the package specific versions. 
I've tried a number of variants of the above, but without any luck.

In the end I ended up making the following changes. I have a feeling 
that this is not the right solution, but I'm at a loss as to a more 
appropriate way of doing what I want. Any suggestions?
