I tried to reproduce on yet another system (x86_64, 128 visible cores
because 4x Intel Xeon Gold 6130, 16 cores/cpu, 2 threads/core), and it
also segfaults.

My guess would be that the test suite depends on the system it is
running on (it just generates the output for the local system), and
there's something it doesn't like about large numbers of cores, but
there's nothing specific to ppc64el here.

There is also
$ grep MAXCPUS -R
src/bootchart.h:#define MAXCPUS        16
src/bootchart.h:        double runtime[MAXCPUS];
src/bootchart.h:        double waittime[MAXCPUS];
src/store.c:                        if (r < 0 || c > MAXCPUS -1)
src/store.c: /* Oops, we only have room for MAXCPUS data */
