+# We run some of the binaries which were just built.
+# This means that if we are cross compiling, we have to configure the
+# package twice: once with the native compiler (this is done in a
+# subdirectory $native_tools), and once with the cross compiler.
+# The former is invoked automatically here, with --host=$build.
+# $native_tools is also added to SUBDIRS in the main Makefile.am,
+# so that make compiles the native tools first.
