+Subject: [PATCH] examples: make examples/ optional
+
+Most users don't need the standalone API examples. Distributions like SUSE
+do not supply libgcc for cross-compiling and we cannot do without on ARMv8
+for building examples/.
+
+Make examples selectable via symbol CONFIG_EXAMPLES. It defaults to
+yes on ARCH_QEMU to ensure that we compile the API as part of our
+continuous integration.
