RH8: Update the call to python to be python2 in migration effort to Red Hat 8

RH7 has /bin/python defined in it's environment whereas RH8 will not.  RH8
will not have a default of /bin/python but will only have /bin/python2 and
/bin/python3 defined.

Considering that for RH7 /bin/python is just a symbolic link to /bin/python2,
making this change to explicitly call python2 will have no detrimental affects
for compiling SBE on RH7 but will position the compiling of the SBE code on
RH8 for success.

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 Blackbird system:

git clone --recursive git@github.com:open-power/op-build.git
cd op-build
./op-build p10ebmc_defconfig && ./op-build

There are also default configurations for other platforms in openpower/configs/. 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
