+# Determine if this is a native build or a cross build.
+#
+# For a cross build add  --define "binutils_target <target>" to the command
+# line when building the rpms.
+#
+# For example:
+#  --define "binutils_target aarch64-linux-gnu"
+#  --define "binutils_target i686-linux-gnu"
+#  --define "binutils_target ppc64le-linux-gnu"
+#  --define "binutils_target s390x-linux-gnu"
+#  --define "binutils_target x86_64-linux-gnu"
+#
+# Cross builds will create a set of binutils that will run on the host
+# machine but which will create binaries suitable for running on the
+# target machine.  The cross tools will have the target name as a prefix.
+# So for example building with --define "binutils_target aarch64-linux-gnu"
+# will create a set of rpms like this:
+#
+#   aarch64-linux-gnu-binutils-2.35.1-14.fc34.x86_64.rpm
+#   aarch64-linux-gnu-binutils-debuginfo-2.35.1-14.fc34.x86_64.rpm
+#   [etc]
+#
+# and these rpms will contain files like:
+#
+#   /usr/bin/aarch64-linux-gnu-addr2line
+#   /usr/bin/aarch64-linux-gnu-ar
+#   /usr/bin/aarch64-linux-gnu-as
