commit b9cf4e3021a3eb9d17d91d02f17b33d930e35bd8

    Avoid ppc64el vector macro in NURBS SQL comments
    
    The ppc64el toolchain can define vector for AltiVec, which makes the SQL preprocessor try to expand bare comment text while building postgis.sql.
    
    Reword the NURBS SQL comments so the preprocessor no longer sees that token.
    
    Closes #6093
    
    Closes https://github.com/postgis/postgis/pull/1159
