And elfutils built with no changes but there were a few problems along
the way. stage2/local.conf has a problem which caused a build failure.
I ended up with this patch which comments out the distcc stuff I'm not
using and the problematic J=1 (should be J=-j1):

diff --git a/stage2/local.conf b/stage2/local.conf

Also, there was a link error with my first attempt to build elfutils. A
failing configure test showed this problem:

--- test.c ---
char lzma_auto_decoder ();
int main()
{
  return lzma_auto_decoder ();
}
---

# gcc test.c -llzma
/usr/lib64/gcc/aarch64-redhat-linux-gnu/4.7.2/../../../../aarch64-redhat-linux-gnu/bin/ld: warning: librt.so.1, needed by /usr/lib64/gcc/aarch64-redhat-linux-gnu/4.7.2/../../../liblzma.so, not found (try using -rpath or -rpath-link)

So this looks like something wrong in the static linker or maybe the
collect2 wrapper. I was able to work around it with:

diff --git a/etc/ld.so.conf b/etc/ld.so.conf
new file mode 100644
index 0000000..4d778f0
--- /dev/null
+++ b/etc/ld.so.conf
@@ -0,0 +1,2 @@
+/lib64
+/usr/lib64

The linker should look in those directories anyway, but for some reason
it isn't.

So, now how do I get the build into the upstream rootfs.git?
