+/* 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. */
