Backporting the DRIVER_SELF_SPECS change fixed all the mdejagnu-cpu
related tests.
Thanks for your help on this.
Consider this patch request withdrawn. I'll resubmit one for the
remaining failing tests for discussion.

From -with-specs= in the configure command. We use that
capability extensively for VxWorks.
We have as DRIVER_SELF_SPECS (see rs6000.h)
#define DRIVER_SELF_SPECS \
"%{mdejagnu-cpu=*: %Interesting.

Apologies on this test, the problem is -mdejagnu-cpu doesn't get matched
by the spec logic
If I pass -mcpu=power8, then indeed the test passes fine.
I'm not sure how to fix this cleanly.

Apparently it doesn't for you, but why is that?
It's likely the specs file we use for the kernel we are

For the test in question: builtins-1-be-folded.c:
The VxWorks header file altivec.h is included by builtins-1.fold.h
and the error is:
altivec.h:34:2: error: #error Use the "-maltivec"
