For x86 and PowerPC there are different possibilities to set the kernel
architecture:
- The old variant for PowerPC is ppc, the newer one is powerpc.
- The old variant for x86 is i386 for 32 bit and x86_64 for 64 bit,
kernels later than 2.6.24 use x86.

Specify extra parameters for the kernel build system here. Useful
options include:
* CONFIG_DEBUG_SECTION_MISMATCH=y
Enable this feature if you want kernel's builsystem to check for
section mismatches (__devinit/__devexit, __init/__exit). This
entry is valid for 2.6.25 kernels and above. Previous kernel versions
do this check automatically. Enabling this feature is recommended
for kernel development.
Changing this entry will rebuild the whole kernel.
* C=1
Run sparse when compiling
* V=1
Increase verbosity when compiling
