[oe] packages versioning

OK, hit a bit of a snag:

PREFERRED_VERSION_wpa-supplicant = "0.7.3"

but this still produces wpa-supplicant_0.6.9-r6.1.6_armv6-novfp.ipk and 
wpa-supplicant-passphrase_0.6.9-r6.1.6_armv6-novfp.ipk. The recipe for 
wpa-supplicant_0.7.3 is there, don't know why isn't used/included. Any 
ideas on what I am doing wrong?

I also found two more errors when trying to include/compile 
xtables-addons - there are two versions available in oe - 1.26 & 1.28. I 
was planning to adapt the newest one (1.28) to compile the latest 
xtables-addons, as well as be able to customise the various modules 
which are included by "default" in this recipe, though I get the 
following errors which prevent building this package and including it 
into the image:

v1.28:
~~~~
ERROR: Task do_unpack in 
/home/mr-4/oe/openembedded/recipes/xtables-addons/xtables-addons_1.28.bb 
depends upon nonexistant task do_populate_staging in 
virtual:native:/home/mr-4/oe/openembedded/recipes/xz/xz_5.0.0.bb

I first thought that there is a dependency missed for including "xz", 
but even if I include this in my local.conf I still get the above error. 
Any idea what is causing this?

v1.26:
~~~~~
arm-oe-linux-gnueabi-ld: unrecognized option '-Wl,-O1'
arm-oe-linux-gnueabi-ld: use the --help option for usage information

That, I suppose, comes from the make linker flags. I am not sure this 
should be included there (shoudn't that be just "-O1"?).
