fix regression in pre-v7 arm on kernels with kuser helper removed
the arm atomics/TLS runtime selection code is called from
__set_thread_area and depends on having libc.auxv and __hwcap
available. commit 71f099cb7db821c51d8f39dfac622c61e54d794c moved the
first call to __set_thread_area to the top of dynamic linking stage 3,
before this data is made available, causing the runtime detection code
to always see __hwcap as zero and thereby select the atomics/TLS
implementations based on kuser helper.
upcoming work on superh will use similar runtime detection.
ideally this early-init code should be cleanly refactored and shared
between the dynamic linker and static-linked startup.
