This adds the dwarfs package.

1. For libdwarf, Guix lint complains that the source archive fails to be
extracted, complaining that 3600 is not a valid date.  Another source
archive is fetched from a fallback source instead.

2. For dwarfs, I've disabled the tests because 1 test fails on 'modprobe
fuse'.  If someone knows how to disable a specific test in the
'googletest' framework, please let me know.

Pierre Neidhardt (2):
  gnu: Add libdwarf.
  gnu: Add dwarfs.

+compressed file system and thus potentially allows for higher cache hit rates
+as more data can be kept in the cache.
+
+@item Highly multi-threaded implementation.  Both the file system creation tool

What is the issue the Git repository?

Because that does not sound good: :-)

Oh right, I can just use the GitHub repo.
Thank you Simon! 
Problem 1 solved then.

I'll push with a note about the tests.
