+/* Dummy crtn file.
+
+   In this configuration, crti.o and crtn.o are both empty because the
+   .init_array/.fini_array sections are used exclusively.
+
+   Older ports cannot use this because even if the linker used to
+   build libc itself has .init_array support, we don't want to produce
+   a crt[in].o that presume a linker that new will be used to link
+   other things later.
+
+   But new configurations without compatibility concerns for
+   toolchains without .init_array support can use this to avoid the
+   superfluous .init and .fini boilerplate code.  */
