skiboot: Fix building device tree with host-dtc

We need to do the build with the PATH set to the host tools. Without
this change the build fails when the host lacks a dtc, as it is not in
the PATH.

I suspect CI missed this as only opal_defconfig tries to build with the
SKIBOOT_DEVICETREE option and the CI that builds this config also
happened to have dtc installed:

$ git grep SKIBOOT_DEVICETREE openpower/configs/
openpower/configs/opal_defconfig:BR2_SKIBOOT_DEVICETREE=y

Note that this will still fail without a skiboot that has "devicetree:
Don't set path to dtc in makefile"[1] applied. This patch won't make any
currently working system fail, so it is safe to merge while we wait for
the skiboot patch to be merged.

OpenPOWER Firmware Build Environment

The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

Documentation

https://open-power.github.io/op-build/

See the doc/ directory for documentation source. Contributions are VERY welcome!

Development

Issues, Milestones, pull requests and code hosting is on GitHub: https://github.com/open-power/op-build

See CONTRIBUTING.md for howto contribute code.

Building an image

To build an image for a Palmetto system:

git clone --recursive git@github.com:open-power/op-build.git
cd op-build
./op-build palmetto_defconfig && ./op-build

There are also default configurations for other platforms in openpower/configs/. Current POWER8 platforms include Habanero, Firestone, and Garrison. Current POWER9 platforms include Witherspoon, Boston (p9dsu), Romulus, and Zaius.

Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.

The machine your building on will need Python 2.7, GCC 6.2 (or later), and a handful of other packages (see below).

Dependencies for 64-bit Ubuntu/Debian systems

  1. Install Ubuntu (>= 18.04) or Debian (>= 9) 64-bit.

  2. Enable Universe (Ubuntu only):
