[Buildroot] [PATCH 1/1] ccache: expose control interface via 'make ccache-options'

[Tzu-Jung Lee <roylee17@gmail.com>]

# Response to patchwork cleanup of week #1

This patch provides an easy way to operate on buildroot ccache such as
changing the cache limit or showing statistics.

Without it, users would have to explicitly specify both the environment variable
and the path of patched ccache, for example:

  BUILDROOT_CACHE_DIR=~/.buildroot-ccache/ $PWD/host/usr/bin/ccache -s
.
Thanks.
