Since the dl_iterate_phdr is required for local unwinding only the use of

This patch seems to eliminate the dependency on dl_phdr_info. I'm not
very familiar with android sources, but bionic seems to define it

Hi Arun,

Thank you for reviewing. The point is that libuwinds remote unwinding functionality has no real dependency to dl_iterate_phdr and therefore should not use the struct dl_phdr_info.
