Thanks for the suggestion, I had completely missed it - I get confused
all the time w.r.t. using the source package name or the binary package
names in the various fields.

I'll shortly send v6 with the following changes:

- install .a in libuuid-dev
- change rdepends on uuid /uuid/libuuid/
- add rdepends on uuid-dev to libuuid-dev
- remove rprovides of libuuid-dev from uuid-dev

The local.conf I am using to test this adds the following lines on top
of the default that's auto-generated:

PACKAGECONFIG_append_pn-util-linux += " cryptsetup"
PACKAGECONFIG_remove_pn-cryptsetup += " blkid"
PREFERRED_PROVIDER_virtual/kernel = "linux-dummy"

Not sure why the issue wasn't seen, I suspect there's some additional
packages that need to be included for it to manifest, although I'm not
sure which.
