[Buildroot] [PATCH] package/util-linux: Fix host uuidd build configuration

[Kory Maincent via buildroot]

The host build had conflicting configuration options where libuuid was
simultaneously enabled and disabled. Although comments explicitly stated
that libuuid should be enabled for the host, the --disable-uuidd flag
was preventing the uuid tools from being built and installed.

Remove the --disable-uuidd configure parameter to allow the uuid tools
to build properly on the host side.

Sorry, but I don't really understand the conflict. --enable-libuuid to
me does not conflict with --disable-uuidd. --enable-libuuid enables the
libuuid library, --disable-uuidd disables the uuidd daemon, which can
optionally be used by libuuid, but isn't strictly needed.

Which specific tool was missing in your case?

Oh wow, my brain read --enable-uuid and --disable-uuid.
uuid and libuuid are indeed two distinct things, sorry for the confusion.

I was needing the uuidgen tool on my case.
That why I need to enable uuid.

And --enable-uuidd controls whether uuidgen is built?

I'll generally be fine with dropping --disable-uiidd, but please
provide a good commit log, explaining the difference in build time
(since it's a host package, we don't care about the difference in
installed size). I presume the build time difference will be minimal if
not negligible.

Yes sure, I will!

In fact this patch is not needed. I was confused about the built result when
having BR2_PACKAGE_HOST_UTIL_LINUX set or not.
If it is set the uuidgen tool is well built.
Sorry for the noise, it seems I need vacation! ;)
