Hi Mark,

we have shared one patch in libc to handle AARCH64_TLS conflict on AARCH64. 
https://sourceware.org/ml/libc-alpha/2015-11/msg00106.html
 
Since we are using cross prelink we don't run testsuite. we compile all test cases 
from test suite manually as mentioned in tls.sh file and run on target. 

LD_DEBUG=libs LD_LIBRARY_PATH=. ./tls1
       
 1828:     prelink checking: ok

....
No segfault or abort() is observed hence i assume testcase is running properly.  

         
Thanks
