[ Upstream commit 0708967e2d56e370231fd07defa0d69f9ad125e8 ]
Building the kernel with ARCH=s390 creates a weird arch/arch/ directory.
$ find arch/arch
arch/arch
arch/arch/s390
arch/arch/s390/include
arch/arch/s390/include/generated
arch/arch/s390/include/generated/asm
arch/arch/s390/include/generated/uapi
arch/arch/s390/include/generated/uapi/asm
The root cause is 'targets' in arch/s390/kernel/syscalls/Makefile,
where the relative path is incorrect.
Strictly speaking, 'targets' was not necessary in the first place
because this Makefile uses 'filechk' instead of 'if_changed'.
However, this commit keeps it, as it will be useful when converting
'filechk' to 'if_changed' later.
