Subject: [PATCH 5.10 050/145] selftests/vm: fix building protection keys test

From: Harish <harish@...ux.ibm.com>

[ Upstream commit 7cf22a1c88c05ea3807f95b1edfebb729016ae52 ]

Commit d8cbe8bfa7d ("tools/testing/selftests/vm: fix build error") tried
to include a ARCH check for powerpc, however ARCH is not defined in the
Makefile before including lib.mk.  This makes test building to skip on
both x86 and powerpc.

Fix the arch check by replacing it using machine type as it is already
defined and used in the test.
