+From 3b7091243ec03054ca8800b51b85a1c09e7e3075 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Remove "check_build_deps" build steps
+
+When building with Bitbake, we want Bitbake to manage our dependencies,
+so we remove the "check_build_deps" steps from Perfetto.
+
+Also setting "is_cross_compiling" to true, so that the host-side tools
+(such as protoc) will always be generated using the native toolchain,
+rather than the Bitbake-generated one.
+
