Subject: bitbake.conf, local.conf.sample: Disable ccache by default
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=337e67cf191963f70006e0ccda90cea2394dbcca;p=openembedded.git

bitbake.conf, local.conf.sample: Disable ccache by default

This moves the current CCACHE over to local.conf.sample and documents
when it's useful to enable.
