Description

In IMPALA-11370, we changed the compilation of Kudu to specify EXTRA_MAKEFLAGS="--load-average=${BUILD_THREADS}". This works fine when Kudu is compiling using Make. However, if Ninja is installed, Kudu will use it. Ninja does not support --load-average, and it will exit immediately.

This is a problem for the ARM jobs that build native-toolchain as part of bootstrap_system.sh. bootstrap_system.sh installs ninja, so this will always fail.
