The problem is that the mkhomedir_helper is built as a library, using a
version-script. This lead to:

  0x70000016 (MIPS_RLD_MAP)               0

Removing --version-script while linking the binary fixes the problem:

  0x70000016 (MIPS_RLD_MAP)               0x413a50

I agree that ld.so should not segfault in that case, I'll try to write a
patch for that, but I don't think the bug is still serious anymore on
the eglibc side.
