build: fix compatibility with meson 0.41 onwards
Versions of meson prior to 0.47 flattened the parameters to the "set_variable" function, which meant that the function could not take array variables as a parameter. Therefore, we need to disable driver tracking for those older versions, in order to maintain compatibility with the minimum supported 0.41 version, and also v0.45 shipped in Ubuntu 18.04 release. Fixes: 806c45dd483d ("build: add configuration summary at end of config") Signed-off-by: Bruce Richardson <bruce.richardson@intel.com> Tested-by: Timothy Redaelli <tredaelli@redhat.com>
