[dpdk-ci] assistance understanding a CI report

[Neil Horman <nhorman@tuxdriver.com>]

Hey all-
	I was wondering if someone could help me untangle what on earth is going
on with this ci report:
http://dpdk.org/ml/archives/test-report/2017-December/036816.html

The error is introduced with the patch associated with that build, and for the
life of me I can't understand whats going on.

experimentalsyms.sh is a script I added to the buildtools withthat patch, and it
runs properly in the local git tree from which I comitted and sent it using gcc
and clang for all the arches I have available to test with (power, x86 and
x86_64).

I don't understand why the ci environment would be having a hard time with
permissions on the script, and don't seem to have any visibility into the ci
environment to diagnose the problem.  The patch in which the script is created:
https://dpdk.org/dev/patchwork/patch/32234/

Correctly indicates that the mode of the file is 0755, which is correct.  But as
soon as I introduce its use in this patch:
https://dpdk.org/dev/patchwork/patch/32237/

It all goes sideways.

Any insight from the ci admins would be appreciated.

Thanks
Neil
