_FILE_OFFSET_BITS=64? fwrite stops at 2gb

Has anyone tried building verilator with _FILE_OFFSET_BITS=64?

I have a sim which generates a log file with fwrite() and it stops cold at 2Gb. I believe this is because _FILE_OFFSET_BITS != 64.

As a hack, I may "#define _FILE_OFFSET_BITS 64" at the top of verilated.cpp and see what happens.

I don't know of a specific trial of this, but think some -m32 distros have this as the default. Plus, Verilator works fine with -m64. If there's any issues the patches should be minor, let us know.
