- Fixed build on Factory, use correct libexec path for symlink

- Added a warning to update.sh, which downloads source code via unencrypted
  svn://, and upstream does not provide a secure download location.

  in the Makefile, while vars specified as make FOO=bar are not.
  Drop CXXOPTFLAGS, which is not used
