fstat appears to be failing for every file (the file= line is printed
right before the fstat; there seems to be a corresponding error for
every file= so I'm inferring that it must always fail):
$ make
HOSTCC scripts/basic/fixdep
file=scripts/basic/.fixdep.d
fixdep: fstat failed: Invalid argument
HOSTCC scripts/basic/docproc
file=scripts/basic/.docproc.d
fixdep: fstat failed: Invalid argument

file=scripts/kconfig/.conf.o.d
fixdep: fstat failed: Invalid argument
file=scripts/kconfig/.kxgettext.o.d
fixdep: fstat failed: Invalid argument
HOSTCC scripts/kconfig/zconf.tab.o
file=scripts/kconfig/.zconf.tab.o.d
fixdep: fstat failed: Invalid argument
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf --silentoldconfig Kconfig

It actually seems as if the problem might be that none of these files
actually exist:
$ find scripts -iname .*.d
$
How are .d files supposed to be generated?

I don't think I do define HOSTCC anywhere. My cross compilation
environment is as follows,
source /usr/local/angstrom/arm/environment-setup
export ARCH=arm
export CROSS_COMPILE=arm-angstrom-linux-gnueabi-
export CC=${CROSS_COMPILE}gcc
export CXX=${CROSS_COMPILE}g++
OE_ENV_ROOT=/home/bgamari/OE/angstrom-dev
SYSROOT=$OE_ENV_ROOT/sysroots/armv7a-angstrom-linux-gnueabi
export LD_LIBRARY_PATH=$SYSROOT/lib:$SYSROOT/usr/lib
export CFLAGS=-I$OE_ROOT/lib/gcc/arm-angstrom-linux-gnueabi/4.3.1/include
