Subject: Config.in: Document BR2_CCACHE_DIR override
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad980ccc3639baa2e517c4d36e836b71ab9f5b8f;p=buildroot.git

Config.in: Document BR2_CCACHE_DIR override

This variable, like BR2_DL_DIR, is designed to be overridable from the
environment.  Unlike BR2_DL_DIR, it is not documented as such in the
Config.in help text.  Do so now.
