"make allmodconfig ARCH=blackfin" cannot work as you need to specify a board...

Hmm, what compiler are you using?
It's odd that __linux__ is not defined...

I built the raw cross compiler from the latest gcc/binutils's upsteam
code:
- binutils:
../binutils-gdb/configure --prefix=/upstream/release-blackfin --target=bfin-gchen-elf --disable-nls --with-sysroot=/upstream/release-blackfin --without-headers target_alias=bfin-gchen-elf
make && make install
[root@localhost build-binutils-blackfin]# /upstream/release-blackfin/bin/bfin-gchen-elf-ld -v
GNU ld (GNU Binutils) 2.25.51.20150401
- gcc:
../gcc-blackfin/configure --target=bfin-gchen-elf --disable-nls --disable-threads --disable-shared --disable-libssp --disable-libquadmath --disable-libgomp --disable-libatomic --prefix=/upstream/release-blackfin --without-headers target_alias=bfin-gchen-elf --enable-languages=c,lto
make all-gcc && make all-target-libgcc && make install
[root@localhost build-binutils-blackfin]# /upstream/release-blackfin/bin/bfin-gchen-elf-gcc -v
Using built-in specs.
COLLECT_GCC=/upstream/release-blackfin/bin/bfin-gchen-elf-gcc
COLLECT_LTO_WRAPPER=/upstream/release-blackfin/libexec/gcc/bfin-gchen-elf/5.0.0/lto-wrapper
Target: bfin-gchen-elf
Configured with: ../gcc-blackfin/configure --target=bfin-gchen-elf --disable-nls --disable-threads --disable-shared --disable-libssp --disable-libquadmath --disable-libgomp --disable-libatomic --prefix=/upstream/release-blackfin --without-headers target_alias=bfin-gchen-elf --enable-languages=c,lto
Thread model: single
gcc version 5.0.0 20150401 (experimental) (GCC)
- kernel using:
make ARCH=blackfin CROSS_COMPILE=/upstream/release-blackfin/bin/bfin-gchen-elf-
Is what I have done above correct? Or can we treate it as gcc's issue?
Thanks.

At least ask gcc folks about that before you add a random hack to the kernel.

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.
