Reverting back to default value of MKARZERO

The value was changed to no for cross-building as the old binutils
could not handle the required flag. As this is now possible, the
default is restored.

This flags make sure that AR zeroes out some timestamps and uid/gid
fields in libraries, which would change for every build of the
library otherwise, preventing comparison between to builds.
