When libbacktrace.a is statically lined to somewhere, that library had
to add libasync_safe.a to static_libs because libbacktrace.a has
references to libasync_safe.a. But libbacktace depending on
libasync_safe is an implementation detail of libbacktrace, and therefore
its client shouldn't be affected by it.
Fixing this by doing the whole static link to libasync_safe to
libbacktrace.a so that the former is included in libbacktrace.a
