Rule #1 when using crosstool: read the comments in the script:
case "$KERNEL_VERSION.$KERNEL_PATCHLEVEL.x" in
2.2.x|2.4.x) make ARCH=$ARCH symlinks include/linux/version.h
2.6.x) case $ARCH in
sh*) # sh does secret stuff in 'make prepare' that can't be triggered separately,
# but happily, it doesn't use target gcc, so we can use it.
# Update: this fails on 2.6.11, as it installs elfconfig.h, which requires target compiler :-(
make ARCH=$ARCH prepare include/linux/version.h
I haven't figured out how to cross-compile 2.6.x for x > 10 for sh,
but then I haven't tried very hard.
