I try following command line:
./configure --target=arm-linux --prefix=$PREFIX $HOST 
--with-headers=$KERNEL/include --with-softfloat-support=multilib-internal 
--without-fp --with-inhibit-libc
make LANGUAGES=c
It compiles. It builds xgcc.
Then it tries to build libgcc and fails, because no valid crti.o and crtn.o 
are available.
I tried also to build --with-softfloat-support=internal : failed at same stage
Next was --with-softfloat-support=multilib-external : failed at same stage

I would be happy to come to that point.

Yep, I did the changes manualy
