dladdr()

[pierre <pierre@silentlife.com>]

Latest musl-libc dladdr() fails here:

   // glibc:
   // gcc hello.c -o hello -ldl
   //
   // ret:1
   // dli_fname:./hello:0x400000
   // dli_sname:puts:0x4004c0

   // musl:
   // musl-gcc hello.c -o hello
   //
   // ret:0
   // dli_fname:(null):0
   // dli_sname:(null):0

   Dl_info dl = {0};
   int ret = dladdr(puts + 0, &dl);

   printf("ret:%d\n"
           "dli_fname:%s:%p\n"
           "dli_sname:%s:%p\n\n",
           ret,
           dl.dli_fname, dl.dli_fbase,
           dl.dli_sname, dl.dli_saddr);

What is missing to make this work?
