TODO: still don't know how to handle dependency on linux .config.

Changes v6->v7:
* Bump version to lastest stable 4.0.1-1.
* Update to current version of kconfig-package.
* Add option to specify config fragments.
* Include upstream patch to fix build error.

Changes v5->v6:
Added changes by Arnout Vandecappelle in Mon Apr 20 21:46:34 UTC 2015:
* linux-backports.mk: $(LINUX_BACKPORTS_KCONFIG_FILE): linux
  this doesn't help: we'd need to use:
  LINUX_BACKPORTS_KCONFIG_FILE := $(LINUX_BACKPORTS_DIR)/defconfigs/$(call qstrip,$(BR2_PACKAGE_LINUX_BACKPORTS_DEFCONFIG))
  but then we don't get value for $(LINUX_BACKPORTS_DIR) nor $(@D).
* linux-backports.mk: LINUX_BACKPORTS_PATCH_DEPENDENCIES = linux
  This also does not help, it does linux extracting, patching, but we
  need also configuring. We'd need something like
  LINUX_BACKPORTS_CONFIGURE_DEPENDENCIES to be implemented.
* Config.in: info about support from kernel 3.0.
* Config.in: help text wrapped to 72 columns.

Changes v4->v5:
* Added changes made by Thomas Petazzoni in Sun, 19 Apr 2015 11:03:26 +0200.

Changes v3->v4:
* Define LINUX_BACKPORTS_MAKE_ENV instead of LINUX_BACKPORTS_MAKE_OPTS, remove TARGET_MAKE_ENV from it.
* Add nconfig to LINUX_BACKPORTS_KCONFIG_EDITORS.
* Clean formating of build commands.
