Subject: build: use ccache -C for cleaning the cache
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=cd5f66652bd405872fc33ca6410dc8f9b51fee09;p=openwrt%2Fstaging%2Fdangole.git

build: use ccache -C for cleaning the cache

This keeps the configuration, like the size of the cache, and the
statistics intact. Move the removal of the cache directory to the
distclean target, but only delete the .ccache directory inside of our
build tree, as we should not mess with a user-configured external ccache
directory this destructively.
