+#if USE_TLS
+  /* Get the dynamic linkers program header.  */
+  ehdr = (ElfW(Ehdr) *) bootstrap_map_p->l_addr;
+  phdr = (ElfW(Phdr) *) (bootstrap_map_p->l_addr + ehdr->e_phoff);

The above 2 will not work with prelink. bootstrap_map_p->l_addr == 0 in that
case. You should use GL(dl_rtld_map).l_map_start instead of
bootstrap_map_p->l_addr (or, if you prefer, (ElfW(Addr)) _begin).

+  for (cnt = 0; cnt < ehdr->e_phnum; ++cnt)
