Log:
  rtld: ignore static TLS segments when tracing.

  For PIE binaries, ldd(1) performs dlopen(RTLD_TRACE) on the binary.
  It is legal for binary to use initial exec TLS mode, but when such
  binary (actually dso) is dlopened, we might not have enough free space
  in the finalized static TLS segment.  Make ldd operational by skipping
  TLS space allocation, we are not going to execute any code from the
  dso anyway.
