note was copied from google-perftools's notice (google-perftools/INSTALL). I
modified the notice because the situation around stacktracer is a bit different
between glog and perftools. Perftool's tcmalloc hooks malloc and its
stacktracer must not call malloc. In glog, stacktracer with malloc can be an
issue only when users use InstallFailureSignalHandler() and a signal is raised
inside malloc.

will dump useful information when the program crashes on certain signals such
as SIGSEGV.
Also, changed the version of autoconf (2.59 => 2.61).

has execinfo.h (e.g., MacOSX 10.5). Though dladdr may not be async
signal safe, it's OK since glog's stacktrace doesn't depend on signals.
