[Buildroot] [PATCH 0/4 v3] core/pkg-kernel-config: ensure linux supports modules (branch yem/kernel-module)

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.

NOTE: The tree is currently *broken* for any package that uses the
kernel-module infra. The release is broken, too.

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.


Thanks to Peter for suggesting the solution, and to Noé and Jan for
their previous attempts that eventually led to this series.


Changes v2 -> v3:
  - add reference to the commit bewing reverted  (Arnout)
  - slight eye-candy, remove trailing colons  (Arnout)

Changes v1 -> v2:
  - do 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.
