PATCH 1/1 locking/atomics: Fix out-of-tree build

From: Borislav Petkov <[email protected]>

Building a kernel out of tree with:

make O=/tmp/b oldconfig
cd /tmp/b
make

gives this:

CALL /mnt/kernel/kernel/linux/scripts/atomic/check-atomics.sh
/bin/bash: scripts/atomic/check-atomics.sh: No such file or directory make[3]: *** [/mnt/kernel/kernel/linux/./Kbuild:86: old-atomics] Error 127 make[3]: *** Waiting for unfinished jobs....

Make the command use the proper build prerequisite which is the absolute path to the script.

Fixes 8d32588077bd ("locking/atomics: Check generated headers are up-to-date")
