Fix it by instead duplicating in linux-headers the 10-20 lines of linux.mk
logic that infer the _SOURCE/_SITE/_VERSION from the BR2_LINUX_KERNEL_*
variables.
This does mean that we extract the kernel sources twice though.
[Peter: use same git/hg tarball as linux kernel to not clone twice, minor fixes]

Some heavily (and most often improperly) modified Linux kernels may export
new APIs to userland, so as to speak to custom hardware or custom kernel
facilities.
However, we currently have no easy way to use such kernels as a source
for the linux-headers package, which precludes having those userland
headers intalled for userland applications to use them.
We do have a way for the kernel to use the same version as for the
headers, but that is definitely not enough, as the linux-headers package
has a version choice that is far less versatile and capable than that of
the linux package.
Add a new option for the linux-headers package, for the user to specify
that the version (really, the sources) of the kernel be used to install
the headers from.
We do that by making linux-headers patch-depend on the linux package.
We can't have linux-header simply depend on linux, because the simple
dependency means the the dependee will be configured, built and installed
before the dependent is configured. And since linux is a target package,
it depends on the toolchain, which internally dependes on linux-headers,
which would depend on linux, and we'd get a circular dependency.
Using patch-depend will ensure that linux is extracted and patched
before linux-headers is extracted, which is really all we need.
Then, we install the headers from the linux source tree, rather than
from linux-headers' source tree (as there's nothing in there!).
Since we need to install a private set for uClibc (see cde947f, uclibc:
prevent rebuilding after installation to staging), we explicitly set
INSTALL_HDR_PATH when calling the kernel' install-headers rule in
LINUX_HEADERS_CONFIGURE_CMDS, so that the headers are installed in
linux-headers' $(@D) instead of linux' $(@D).
Finally, as there is no way to know the kernel version in this case, we
must still prompt the user for the kernel series the headers are from
(like we do for a custom version) and check for consistency at build
time.
Note however that this still leaves users that want to built their
such-kernel outside of Buildroot out in the cold.

Now that we check that a target package in the _DEPENDENCIES of another
package has to be enabled in config, all target packages must have a
kconfig symbol.
Add a Kconfig symbol for linux-headers, and select it from the packages
that depends on it (C libraries).
Also remove the now-misleading comments "for legal-info" from the C
libraries.
