Coverity scan complained about expression "|LARGEFILE" to be non reachable
and the detailed Coverity report claims O_LARGEFILE was zero. I can't
reproduce this here, but I assume that means there are at least some
system(s) which define O_LARGEFILE as zero.

This is not really an issue, but to silence this Coverity warning, add a
preprocessor wrapper that checks for O_LARGEFILE being non-zero for this
overall expression. The 'defined(O_LARGEFILE)' check is not necessary,
but it makes it more clear that we really want to check for the value of
O_LARGEFILE, not just whether the macro was defined.
