Use CMake's dependency resolution always instead of serial execution of targets via shell scripts. This improves parallelism by building fe, be, and other targets at the same time and avoid some overhead from invoking "make" multiple times. This reduces the time taken for an incremental compilation of fe and be from 56s to 24s with this command: ./buildall.sh -debug -noclean -notests -skiptests -ninja Also use Impala-lzo's build script. This depends on the IMPALA-4277 fixes to the Impala-lzo build script. Log directory creation is also moved from impala-config.sh to buildall.sh. This means that impala-config.sh has no side-effects and can be run concurrently with no issues. Also make sure that "make" builds all the same artifacts as buildall.sh when run with no args. Testing: Ran a jenkins core job, also experimented locally. Ran a jenkins core job with distcc disabled - this exposed some concurrency bugs where impala-config.sh fails if run concurrently.
