Commit 0a0e2ea642f6 ("ACPI: processor: Move MWAIT quirk out of acpi_processor.c") added acpi_proc_quirk_mwait_check() that is only defined for x86 and is unlikely to be defined for any other architectures, so put it under #ifdef CONFIG_X86 and provide an empty stub implementation of it for the other cases.

This is kind of orthogonal to
https://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux.git/commit/?h=remove-ia64&id=a0334bf78b95532cec54f56b53e8ae1bfe7e1ca1
because if any architectures other than x86 and ia64 decide to use the processor _OSC, they will see the reported build error.
