[Buildroot] pkgconf patch set can be applied

[Thomas Petazzoni]

Peter,

I did test the pkgconf work from Gustavo on some configurations here. I
found some problems and together with Gustavo we fixed them, which led
Gustavo to send a v7 for the pkgconf package itself.

So now, I think that the following patches can be applied:

 [PATCHv7 1/5] pkgconf: new package
 [PATCHv6 2/5] packages: switch to host-pkgconf
 [PATCHv6 3/5] pkg-config: remove host variant
 [PATCHv6 4/5] pkg-config: mark as deprecated
 [PATCHv6 5/5] iw: pkg-config cleanup

Of course, it is a fairly significant modification, so we will probably
have issues, but only a more large scale testing with the autobuilders
can tell us. So let's apply these and see what happens.

Thanks,

Thomas
