/* Dummy crti 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. */
