Fail building 2.6.31.x for CHRP using gcc-4.4.x

[Giuseppe Coviello]

Hi, we are having trouble while building kernel 2.6.31.x and also
2.6.32rc for CHRP platforms using gcc-4.4.x, the error that give us
the compilation is:

  CC      arch/powerpc/sysdev/indirect_pci.o
  CC      arch/powerpc/sysdev/i8259.o
  LD      arch/powerpc/sysdev/built-in.o
  CC      arch/powerpc/platforms/chrp/setup.o
cc1: warnings being treated as errors
arch/powerpc/platforms/chrp/setup.c: In function 'chrp_event_scan':
arch/powerpc/platforms/chrp/setup.c:378: error: the frame size of 1040
bytes is larger than 1024 bytes
make[2]: *** [arch/powerpc/platforms/chrp/setup.o] Error 1
make[1]: *** [arch/powerpc/platforms/chrp] Error 2
make: *** [arch/powerpc/platforms] Error

The same kernel, with the same configuration builds fine using gcc-4.3.x.

Regards, Giuseppe

For now, just enable CONFIG_PPC_DISABLE_WERROR.
