Alex Suykov 75630eba22 core: do not attempt downloads with no _VERSION set
Currently, when the package defines no _SOURCE and no _VERSION
variables, we end up trying to download <PACKAGE>-undefined.tar.gz.

This is utterly pointless.

Change the logic to not attempt a download when neither _SOURCE
nor _VERSION is set:
  - do not set an undefined _VERSION to "undefined"
  - do not append an empty (or "undefined") version to the package
    rawname

Consequently, for packages that have no _VERSION, the build
directory will be just the package name (which to some may look
nicer than the current "package-undefined").

Furthermore, the message trace is also a bit leaner (to the same
people that find "package" nicer than "package-undefined").

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
