You have to modify src/tools/EpicsHostArch.pl to match your platform.
Here is the example, which was for the ESS Linux.

https://github.com/jeonghanlee/e3-base-4-timo/blob/master/patch/Site/R7.0.3.1/ess_epics_host_arch.p0.patch

Then, you have to modify the following file in order to match the
QorIQ SDK, I think, this should be very minimal, and put them into
your base configure/os/ path.

https://github.com/jeonghanlee/e3-base-4-timo/blob/master/configure/os/CONFIG_SITE.Common.linux-ppc64e6500

Please replace linux-ppc64e6500 according to what you define in
EpicsHostArch as well.

Then, you can build the EPICS base properly. That configuration file
is independent of the ESS E3. That is the generic configuration for
the EPICS base.

If you can share your SDK with me, I may modify this configuration file for you.

Best,
Han
