linking error under ubuntu 12

[Daniel Graczer]

hi, I am trying to compile strace under Ubuntu 12, and it succeeds
initially. However if I define the USE_LIBINWIND macro in config.h.in( I
want to use the -k option for stack trace) the linking fails. I tried to
manually link against the libunwind library, but that library doesn't have
the functions strace is complaining about.
