On x86 rcutorture builds successfully.  However, allmodconfig
on semi-recent -next got me "Can't open perl script
"./usr/include/headers_check.pl": No such file or directory".
Which might well be a local problem or might well be fixed by now.

Either way, it looks like I need to upgrade the torture.sh script's
checks for failed builds.  Thank you for reporting this!
