Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
wolfssl could not be built reproducibly.
This is because it used ar's "U" argument to deliberately inherit the
build system's filesystem timestamps, umask, etc. I do not know why
this was introduced and am assuming it is merely a debugging thing.
Patch attached that simply removes this behaviour.
