Since Linux 3.18-rc1, Kbuild is able to handle multi-objs dependency correctly, which also allows us futher cleanups of some makefiles.

This commit imports those commits:

[1] commit c8589d1e9e01 by Masahiro Yamada kbuild: handle multi-objs dependency appropriately

[2] commit 97e3226e6e98 by Masahiro Yamada kbuild: handle the dependency of multi-objs hostprogs appropriately

[3] commit 022af62d0190 by Masahiro Yamada kbuild: refactor script/kconfig/Makefile

Since Linux 3.15, relative path feature and related fixes, cleanups have been merged to the top Makefile.

The relative path feature looks stable enough, so let's import it to U-Boot along with various cleanups.

Commits imported from Linux (some need adjustment) are:

[1] commit 7e1c04779efd by Michal Marek kbuild: Use relative path for $(objtree)

[2] commit 890676c65d69 by Michal Marek kbuild: Use relative path when building in the source tree

[3] commit 9da0763bdd82 by Michal Marek kbuild: Use relative path when building in a subdir of the source tree

[4] commit c2e28dc975ea by Michal Marek kbuild: Print the name of the build directory

[5] commit 066b7ed95580 by Michal Marek kbuild: Do not print the build directory with make -s

[6] commit 3f1d9a6cec01 by Michal Marek kbuild: make -s should be used with kernelrelease/kernelversion/image_name

[7] commit 7ff525712acf by Masahiro Yamada kbuild: fake the "Entering directory ..." message more simply

[8] commit 745a254322c8 by Masahiro Yamada kbuild: use $(Q) for sub-make target

[9] commit aa55c8e2f7a3 by Masahiro Yamada kbuild: handle C=... and M=... after entering into build directory

[10] commit ab7474ea5361 by Borislav Petkov Kbuild: Ignore GREP_OPTIONS env variable

To use relative path feature, tools/Makefile and scripts/Makefile.autoconf must be tweaked.

This commit imports Kconfig updates from Linux 3.18-rc1.

'kvmconfig' and 'tinyconfig' help message have been commented out since they are unavailable at least now; in the future perhaps we can implement 'tinyconfig' to disable most of CONFIG_CMD_* to create a very small U-Boot image.

[1] commit 3aaefce10351 by Josh Triplett x86, platform, kconfig: move kvmconfig functionality to a helper

[2] commit 0da1d4a0b951 by Josh Triplett x86: Add "make tinyconfig" to configure the tiniest possible kernel

[3] commit c40724d3f381 by Brian Norris kconfig: lxdialog: fix spelling

[4] commit 7285996aa000 by Brian Norris kconfig: nconfig: fix multi-byte UTF handling
