Ok, I managed now to build a libnss_nis.so.2 module, which uses
thread local storage instead of static variables and locking.

Now my next problem: SuSE and RH have the libc/libpthread with TLS
and NPTL support in /lib/tls and a version without in /lib. But the
path to the libnss_* modules is hardcoded to /lib/libnss_*. So I cannot
copy the libnss_nis module with TLS support into /lib/tls/.

Any ideas how to solve this?

 Thanks,
    Thorsten
