Subject: [PATCH] Revert "ccache: update to 4.1"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit b1952dc259ce3eb7ac6023c9e02d5adf2546efca as it's
causing issues on the buildbot which uses some kind of ccache wrapper
and so the breakage needs to be investigated further:

 bash: cmake: command not found
 time: tools/ccache/compile#0.05#0.03#0.15
     ERROR: tools/ccache failed to build.
