 3927 magnus.blaudd@stripped	2012-09-05
      ndb
       - add the code for generating module definition file as PRE_BUILD
         step on Windows to CMakelists.txt since it will cause more symbols
         than we have today to be exported
       - improve comments

       - The ndbNDBT library uses sqrt() from math lib, link with LIBM

       - Only remove non system libs from the transitive linking
         list in ndbclient_so, i.e remove the ones which are built
         by this build
