    XL: Drop -qalias=noansi from default C flags
    
    This was added without explanation by commit v2.8.2~1138 (Add initial XL
    C compiler flags for safer builds, 2009-09-30).  It is not consistent
    with our default C++ flags for XL and disables several optimizations, so
    drop it from our default flags for C.
