This looks right and reduces the stat usages in libjava down to one 
remaining case (ProcessHandlerImpl_linux.c).

Some sources are using _ALLBSD_SOURCE, I think this dates back to the 
Apple/BSD patch (went into 7u4 and 8). So there is a bit of consistency 
that should be cleaned up some time. Apple may have had a 32-bit build 
of the JDK many years ago but the changes that were into OpenJDK were 
for building on 64-bit only.
