This introduces debuginfod support which requires a couple of new inputs.

* gnu/packages/elf.scm (elfutils): Update to 0.178
  [native-inputs]: Add iproute and pkg-config.
  [inputs]: Add cpio, libarchive, libmicrohttpd, libcurl, rpm and sqlite.
* gnu/packages/patches/elfutils-tests-ptrace.patch: Removed. Fixed upstream.
* gnu/packages/patches/elfutils-0.178-tests-build-id.patch: New. Patches
  backported from upstream git.

Hi Mark! Funny you submitted this, I was working on the same package about an hour ago. We must be reading each other's minds. You got significantly farther than I did. One thing I did do differently was that I extended the list of licenses to include the ones mentioned in the comment.

I'll look at your patch, and hopefully this will be ready for core-updates. Thank you :)

Thanks for looking at it. This is my first guix patch, so please be
gentle. I do maintain elfutils upstream, so I did have a little
advantage picking some upstream patches which hadn't gone into the
release yet.

Good you mention the licenses. I forgot to update them licenses. 0.178
introduces some new documentation (man pages), one of them is under
the GFDL (without invariant sections).

Also I am not sure how precisely we should mention the dual
gplv2+/lgplv3+ license for the "out" output libraries and the gplv3+
license for the "bin" output (and where the gfdl should be added).

Thanks,

Mark

+    Make sure to always build with build-ids.
+    
+    We really need build-ids for various things.  If the system compiler
+    doesn't generate build-ids warn and generate them anyway for both the
