The _dl_printf() used to be used in libexec/ld.so/*/archdep.h if an
unexpected type of relocation was encountered in ld.so itself. Those went
away (we test ld.so before installing it; _dl_exit() is enough) so the
static pie bits in lib/csu/*/md_init.h no longer need to supply a
no-op _dl_printf() stub.
ok?
