[poppler] [PATCH] Use fseeko64/ftello64 for MinGW32

[Peter Breitenlohner]

Hi,

In MinGW32 (3.20) the prototypes for _fseeki64/_ftelli64 are available when
__MSVCRT_VERSION__ >= 0x800 but this then requires to link with
libmsvcr80.a, i.e., msvcr80.dll or better.

Since MinGW32 provides fseeko64/ftello64 why not use those as per this
patch:
