Description of problem:

lack of support for thread local storage in the emulation mode
---------------------------------------------------------------
The compatibility libraries are insufficient to support complex and 
multi-threaded applications."

Looking at the kernel source there are a number of calls not 
implemented which appear to be required by threaded applications.
         set_thread_area
         get_thread_area
         sys_exit_group
         sys_set_tid_address
 
The work to get these to work has been done in both the 2.6 kernels, 
and the 2.4.x kernels for the x86_64 AMD chip. 

An example of a program which does not work under emulation mode.

#include <stdio.h>
#include <stdlib.h>
main()
{
        printf("system(date) retuned = %d\n", system("date"));
}

An strace shows it first reports a missing 'set_thread_area' syscall 
not being implemented, and then fails on a clone call. This is the 
same as I see when I run a simple threaded program under emulation.

Version-Release number of selected component (if applicable):

RHEL 3 IA-64


Steps to Reproduce:

see example program above.
