For the latest compiler, it should contents -D__linux__, and what I have
done for building gcc/binutils is the common way, so I guess binutils or
gcc need improvement (I shall try to fix it within this month).

But, I am not quite sure whether the old version bfin compilers also
supports -D__linux__ (comparing some of the old compilers of the other
archs, I guess not). Are you sure the old version bfin compilers are OK?


BTW, for the latest bfin compiler from upstream, it contents another
issues which I bypassed now. I shall try to fix them within this month
(try to send all fix patches v1 within 2015-04-20).


Thanks.
