Bug#180530: PPC32: Segfault when compiling the kernel (2.4.20)

[Matthias Klose <doko@cs.tu-berlin.de>]

We need more information:

- please send the preprocessed (maybe compressed) file init.i
- show the compilation options used
- please try to compile with the gcc from the gcc-snapshot package

Thanks, Matthias
