[Buildroot] [PATCH 0/4 v2] core/pkg-kernel-config: ensure linux supports modules (branch yem/kernel-module)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This series fixes two standing issues with the way we handle packages
that build kernel modules:

  - first, the current check is broken, because $(LINUX_DIR) should be
    double-$ed, as it is used in a macro from an infra,

  - second, it is currently possible to (try to) build such packages
    without the kernel config havong CONFIG_MODULES set.

So, these three patches fix that:

  - introduce a new internal variable to tell the kernel to enable
    support for modules, LINUX_NEEDS_MODULES, that should be set
    whenever a package wants to build a kernel modules, and is
    automatically set by the kernel-module infra,

  - the (broken) check is no longer needed so removed,

  - a few packages that build kernel modules without using the
    kernel-module infra are fixed to manually set that variable.

I believe that should go into master, because:

  - it actually fixes build issues

  - the kernel-module infra is brand new in this release, and should be
    fixed and stable prior to being released to the wide hostile world
    ;-)

Thanks to Peter for suggesting the solution, and to No? and Jan for
their previous attempts that eventually led to this series.

Changes v1 -> v2:
  - to not force CONFIG_MODULES if requesting package is not enabled
    (Peter, Jan)
  - update commit log that the check was broken anyway
  - add 4th patch to slightly improve linux-fusion


Regards,
Yann E. MORIN.
