[ptxdist] [PATCH] kernel: Replace PTXCONF_KERNEL_ARCH_STRING with GENERIC_KERNEL_ARCH

[Sascha Hauer <s.hauer@pengutronix.de>]

PTXCONF_KERNEL_ARCH_STRING is used for cases when for a given ptxdist
architecture multiple kernel architectures exist. This only happens on
more than 10 year old Kernels, it's time to remove this compatibility
cruft. We can now use GENERIC_KERNEL_ARCH which has the same purpose and
is used in other places already, but doesn't handle the multiple kernel
architecture case.

PTXCONF_KERNEL_ARCH_STRING was useful on PowerPC where the kernel
architectures "ppc" and "powerpc" existed and on x86 where we had "i386"
and "x86_64". These are stories from the old days, since v2.6.24 we only
have "x86" for all x86 machines and since v2.6.27 we only have "powerpc"
for all powerpc machines.
