[Ltib] config option use BSP kernel headers with >= linux-2.6.17

[Aaron Wegner]

Going through the Git log of the Linux kernel it seems like there has been
a basic implementation of 'make headers_install' since about 2.6.17.  I
was trying to install the headers of a 3.8 kernel and running into some
problems.  I seemed to be able to overcome these by editing
dist/lfs-5.1/kernel/kernel-common.tmpl and replacing the
PKG_KERNEL_WANT_HEADERS section with the following.

if [ -n "$PKG_KERNEL_WANT_HEADERS" ]
then
    make ARCH=$LINTARCH HOSTCC="$BUILDCC"
INSTALL_HDR_PATH=$RPM_BUILD_ROOT/%{pfx}/usr/src/linux headers_install
fi

Maybe this could be a patch?  Not exactly sure how to specify the
condition that the kernel version is greater than or equal to one in which
the 'make headers_install' is working well, but for recent kernels the
current LTIB spec file fails since the includes are reordered from the old
way.


Thanks,
