If you don't have emulated TLS, your build shouldn't even succeed 
if you haven't implemented __tls_get_address. So if you have a 
build that you can test, where does this __tls_get_address come 
from? Another possibility is that you can use the thread pointer 
register directly and not use __aeabi_read_tp.__aeabi_read_tp is 
basically the function that is used for obtaining the thread 
pointer by SW instead for initial exec model.
