CROSS_COMPILE not taken into account on parisc64?

CROSS_COMPILE not taken into account on parisc64?

[Meelis Roos]

I am trying to build 2.6.33-rc* for a 64-bit parisc machine (using 
kernel.package in Debian unstable if it matters). The build 
fails assembling any .ko files with objcopy:

objcopy --add-gnu-debuglink=/home/mroos/linux-2.6/debian/linux-image-2.6.33-rc8-00173-g627fa17/usr/lib/debug/lib/modules/2.6.33-rc8-00173-g627fa17/kernel/drivers/cdrom/cdrom.ko /home/mroos/linux-2.6/debian/linux-image-2.6.33-rc8-00173-g627fa17/lib/modules/2.6.33-rc8-00173-g627fa17/kernel/drivers/cdrom/cdrom.ko
objcopy:/home/mroos/linux-2.6/debian/linux-image-2.6.33-rc8-00173-g627fa17/lib/modules/2.6.33-rc8-00173-g627fa17/kernel/drivers/cdrom/cdrom.ko: File format not recognized

Trying hppa64-linux-gnu-objcopy by hand works - but we should be using 
this cross compile prefix automatically.

We do have
OBJDUMP         = $(CROSS_COMPILE)objdump
in main Makefile, and

ifdef CONFIG_64BIT
UTS_MACHINE     := parisc64
CHECKFLAGS      += -D__LP64__=1 -m64
WIDTH           := 64
CROSS_COMPILE   := hppa64-linux-gnu-
else # 32-bit
WIDTH           :=
endif

in arch/parisc/Makefile so it seems OK at the first glance.

grep 64BIT .config tells
CONFIG_64BIT=y
CONFIG_PHYS_ADDR_T_64BIT=y

so this is correct too.

However, I see no inclusion of arch-specific Makefile before the 
assignment of OBJCOPY in main Makefile. Could this be the problem?

I guess this objcopy command is run outside of the kernel build system
(a packaging script storing debug info in /usr/lib/debug), nothing the
kernel makefiles can do about.

That's OK, make variables assigned with '=' are expanded when they are used.

Thanks - my bad that I didn't notice this.
