ok, reproduced..
the commit changes the output of the depfile for some reason,
and our fixdep does not handle it correctly and produce wrong
cmd file that failed to parse.. checking for fix
depfile changes ('+' is after the change):
-plugin_jbd2.o: plugin_jbd2.c /usr/include/stdc-predef.h \
+plugin_jbd2.o plugin_jbd2.o: plugin_jbd2.c /usr/include/stdc-predef.h \
