Subject: [PATCH] Fixed unforeseen definition of O_LARGEFILE=1

By setting -DO_LARGEFILE on the cmake command line, it is actually the same as
setting -DO_LARGEFILE=1. Since this constant is used inside code to set flags,
a file would be opened with both READ_ONLY and READ_WRITE flag set.
This of course will not be allowed by the kernel
