proper generic 64bit/crosscompilation ARCH/flags selection

[Eduard Bloch <edi@gmx.de>]

Hello,

I would like to get more competent comments from concerned kernel
packages on the issue quoted below. There is already a hack for sparc64:

ifeq ($(ARCH),)
SPARCH=$(shell grep 'CONFIG_SPARC..=y' "$(KSRC)/.config" 2>/dev/null| cut -d= -f1)
#maybe a different ARCH on sparc
ifeq (CONFIG_SPARC32,$(SPARCH))
ARCH :=sparc
export ARCH
endif
ifeq (CONFIG_SPARC64,$(SPARCH))
ARCH :=sparc64
export ARCH
endif
endif
