+From ca5ee0e918115fb5cf626d75461d9fca06e06caf Mon Sep 17 00:00:00 2001

+Subject: [PATCH] tools: hv: Fix cross-compilation
+
+Use the native ARCH only in case it is not set, this will allow the
+cross-compilation where ARCH is explicitly set.
+
+Additionally, simplify the ARCH check to build the fcopy daemon only
+for x86 and x86_64.
+
+Fixes: 82b0945ce2c2 ("tools: hv: Add new fcopy application based on uio driver")
