Subject: checkinstall: Segmentation fault when invoking `checkinstall cmake -P cmake_install.cmake`
Forwarded: https://bugtrack.izto.org:4442/show_bug.cgi?id=171

in installwatch.c, _xstat64() is missing check for initialization

As a consequence of this, if `__xstat64()` is the first function called from
the library, then no initialization is performed and the program segfaults when
trying to call `true_xstat64()` which is uninitialized

This causes a segmentation fault on Debian Stretch when invoking e.g.:
`checkinstall cmake -P cmake_install.cmake`
