[Buildroot] [PATCH v2] Makefile: Remove 'quiet' variable

[Cédric Marie]

'quiet' variable is set and exported, but it is not used. We can safely
remove it.

This variable is inherited from the Makefile of the Linux kernel, and
is not used in Buildroot.

In support/scripts/mkmakefile, 'quiet' value is checked, but the test
is always true ('quiet' is never set to silent_), so the test can be
removed as well.

Changes v1 -> v2:
  - KBUILD_VERBOSE must not be removed, it is used for packages based
    on Kbuild.

Title of PATCH v1 was:
Makefile: Remove KBUILD_VERBOSE and quiet

In order to describe how the verbosity level is managed in different
infrastructures, comments will be added in Makefile (suggested by Arnout).
It will be provided in a separate patch.

Arnout also suggested not to export 'Q', which seems to be Buildroot
internal. This will also be provided in a separate patch, if confirmed.
