It was added here:

 Add initial XL C compiler flags for safer builds
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=e1729238

but I don't recall why it was included among the other defaults
and the commit message doesn't say anything about it :(

Yes, we can try dropping it:

 XL: Drop -qalias=noansi from default C flags
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=a33fb493

Thanks,
