Subject: Problems building 2.6.31.6 with 64bit Fedora-11

OK, Im new to Fedora-11, and this will be my first 64bit
kernel build, so this is probably going to be something
stupid, but I dont see it.

The top of my .config file reads:

---

#
# Automatically generated make config: don't edit
# Linux kernel version: 2.6.31.6-PPS
# Thu Nov 19 20:08:27 2009
#
CONFIG_64BIT=y
# CONFIG_X86_32 is not set
CONFIG_X86_64=y
CONFIG_X86=y
CONFIG_OUTPUT_FORMAT="elf64-x86-64"
CONFIG_ARCH_DEFCONFIG="arch/x86/configs/x86_64_defconfig"
CONFIG_GENERIC_TIME=y
CONFIG_GENERIC_CMOS_UPDATE=y
CONFIG_CLOCKSOURCE_WATCHDOG=y
CONFIG_GENERIC_CLOCKEVENTS=y

--- 

So it seems that I am really doing a 64bit build, but the problems
start with the first cc/ld, viz
