Will the IDLE TLS size be based on the

libdl once it supports loading TLS based code.
Currently, only the actual TLS size is used. We would have to change
_TLS_Get_allocation_size() to use the maximum if it is non-zero.
It would be good to get this sorted and in before a push is made on libdl to
support TLS. I think the newlib change will make TLS a visible issue in libdl in
6 so it needs to be fixed.
I checked _TLS_Get_allocation_size(). It already returns the maximum
size if it is configured:
if ( _Thread_Maximum_TLS_size != 0 ) {
if ( allocation_size <= _Thread_Maximum_TLS_size ) {
_Assert( _Thread_Maximum_TLS_size % CPU_STACK_ALIGNMENT == 0 );
allocation_size = _Thread_Maximum_TLS_size;
} else {
_Internal_error( INTERNAL_ERROR_TOO_LARGE_TLS_SIZE );
}
}
