makeinfo is missing from build-tools. I had to manually build one and install it in the build-tools. Bitmake complains if there is no makeinfo.
buildtools-tarball doesn't contain absolutely all the dependencies the build system needs - only those we know to be broken on common distributions. Were you not able to install the package providing makeinfo on your host distro? If not, which host distro was that with?
Host distro is Redhat Enterprise 6.7 With the exception of problems fetching "e2fsprogs" tarball and makeinfo, all is well on Redhat Enterprise 6.7 and I was able to successfully build and run a sato PowerPC image. Please note this would a nice addition to the buildtools-tarball and if not possible, we can always document internally to bootstrap "makeinfo" into the buildtools and/or update our Redhat 6.7 distro to include "textinfo" package. No worries.
