Does it make sense to move the O_LARGEFILE definition to bits/fcntl-linux.h
instead, i.e. if __O_LARGEFILE is not defined, provide a definition that's
conditional on _WORDSIZE?  That seems like a more natural default,
particularly as more platforms will be 64-bit with time and thus want zero
for O_LARGEFILE.  <bits/wordsize.h> could either be unconditionally
included, or just included ifndef __O_LARGEFILE.

Likewise, it might make sense to take the linux-generic version of struct
flock/flock64 into bits/fcntl-linux.h, with an "#ifndef __struct_flock" or
equivalent so that platforms with variant definitions of those structures
can provide them.

This would leave us in the natural-seeming position of having linux-generic
use the generic Linux version of fcntl.h with no customizations :-)
