+commit 44da99781e5bb954a0cd3c897b859012a125fec6
+Author: Mark Wielaard <mark@klomp.org>

+
+    unhandled ppc64le-linux syscall: 252 (statfs64) and 253 (fstatfs64)
+    
+    glibc 2.34 consolidated all statfs implementations. All other arches
+    that have statfs64/fstat64 (including ppc32) already had that syscall
+    hooked up, it was just ppc64 that was missing it.
