+# - Bootstrap aarch64 using static build provided by Alpine
+#   This is necessary because Crystal is a self hosted compiler and
+#   it can be removed on the first package upgrade. That is move crystal back
+#   to the general makedepends, as  it guarantees being able to build the current
+#   release with the previous one.
+# - Pull in patches needed for  aarch64 compatibility
