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