A static, none thread patch

I'd like to see them in 2.1.2 branch. I cannot use 2.2 for ia64. I
need a known working, stable C library for ia64.

As I said, I got it when I configured glibc as static only on ia32.
I got

----trusted-dirs.h---
#define SYSTEM_DIRS \
  ""

#define SYSTEM_DIRS_LEN \
  0

#define SYSTEM_DIRS_MAX_LEN     0
----

Maybe it is due to there is no run-time linker configured.

I will see if it is needed for ia64 when everything is there.

Thanks.
