I think the name is what it does. It enables openjdk's cross-compilation
support. At the moment this consists only of disabling the sanity checks
but the next patch will handle calling 'uname -m' in certain places. As
such I argue --disable-cc-incompatible-sanity-checks is not a good
option (except you want 3 options related to cross-compilation in the end).
