[Patch, fortran] PR 39654 FTELL intrinsic

Hi,

the attached patch makes the FTELL intrinsic function work on offsets
larger than 2 GB on 32-bit systems that support large files. As this
is an ABI change the old library function is left untouched, to be
removed when/if the library ABI is bumped.

Regtested on x86_64-unknown-linux-gnu, Ok for trunk?
