For at least two reasons: - exposes sneaky change(s) performed by automation if/when any - solves the mystery of the Source content hash (printed on the next line) changing while the git version does not. Example, at https://sof-ci.01.org/sofpr/PR3941/build8429/build/bdw_gcc.txt -- Found Git: /usr/bin/git (found version "2.17.1") -- GIT_TAG / GIT_LOG_HASH : v1.7-rc1-151-g023c4abacde1 / 023c4abac -- Source content hash: 91f261ea whereas at https://github.com/thesofproject/sof/runs/2166298087, xtensa-build-all: -- Found Git: /usr/bin/git (found version "2.17.1") -- GIT_TAG / GIT_LOG_HASH : v1.7-rc1-151-g023c4abacde1 / 023c4abac -- Source content hash: 67f31697 Signed-off-by: Marc Herbert <marc.herbert@intel.com>
