Subject: [PATCH] tools/mksymtab.sh: Support symbol name overriding

The lines start with "," make no effects(as comments)

e.g.
  $ cat exports.txt | grep atan2
  atan2Override,atan2

  $ /PATH/TO/APPS/tools/mksymtab.sh FOO BAR exports.txt | grep atan2
  extern void *atan2Override;
    {"atan2", &atan2Override},
