Wait - this seems to be produced even with the current glibc without my 
changes (glibc compiled by GCC 3.3):
nm /lib64/ld-linux-x86-64.so.2 |grep elf_machine_rela
0000000000000d40 t elf_machine_rela.0
0000000000007fa0 t elf_machine_rela.0
000000000000d010 t elf_machine_rela.0
0000000000000d70 t elf_machine_rela_relative.1
0000000000008330 t elf_machine_rela_relative.1

For reference, compile:
int
test (int j)
{
  
static  inline int
    __attribute__ ((always_inline))
    test_inline (int i)
    {
      return i++;
    }
  
  return test_inline (j);
}

I get with GCC 3.3:
gromit:/tmp:[0]$ gcc -Wall -c t.c -O2
gromit:/tmp:[0]$ nm t.o
0000000000000010 T test
0000000000000000 t test_inline.0

But with 3.4 (and also 3.5 removing the static):
gromit:/tmp:[0]$ /opt/gcc/3.4-devel/bin/gcc -Wall -c t.c -O2
gromit:/tmp:[0]$ nm t.o
0000000000000000 T test


It's a local entry point in 3.3.

The local entry point exists for me with both 3.3 and 3.5 in dl-reloc.o.

I guess we should go with my patch.  Ok?
