Not sure if you're still interested, but I had already fired the
regression test anyway:

This patch introduces the following regressions in ppc64-linux:

 PASS: gdb.base/auxv.exp: generate native core dump
 PASS: gdb.base/auxv.exp: load core file for info auxv on native core dump
 PASS: gdb.base/auxv.exp: info auxv on native core dump
-PASS: gdb.base/auxv.exp: matching auxv data from live and core
+FAIL: gdb.base/auxv.exp: matching auxv data from live and core
 PASS: gdb.base/auxv.exp: load core file for info auxv on gcore-created dump
 PASS: gdb.base/auxv.exp: info auxv on gcore-created dump
-PASS: gdb.base/auxv.exp: matching auxv data from live and gcore
+FAIL: gdb.base/auxv.exp: matching auxv data from live and gcore

Here's the gdb.log for the failing run:

info auxv^M
0    AT_NULL              End of vector                  0x16^M
(gdb) PASS: gdb.base/auxv.exp: info auxv on native core dump
FAIL: gdb.base/auxv.exp: matching auxv data from live and core

Versus the gdb.log for the successful run:
