[Buildroot] PowerPC kernel headers

[Fredrik Roubert]

Hi!

Recently the possibility to use the Linux 2.6.18 kernel headers has been
added to buildroot. However, the correct asm directory for PowerPC has
changed from "ppc" to "powerpc", as part of the move to a unified kernel
architecture for 32 and 64 bit PowerPC system.

The attached patch updates kernel-headers.mk to use asm-powerpc when
building with the 2.6.18 kernel headers.

Cheers // Fredrik Roubert
