  Log:
    remove DISABLE_RUBYGEMS from config files
    
    * configure.ac: removed DISABLE_RUBYGEMS macro from config.h, not
      to rebuild everything when the flag changed.
    
    * configure.ac, win32/configure.bat: make USE_RUBYGEMS lowercase.
    
    * tool/mkconfig.rb: remove RUBYGEMS stuff from rbconfig.rb, not to
      reconfigure and rebuild all extension libraries.
    
    * Makefile.in (CPPFLAGS): enable/disable Rubygems by USE_RUBYGEMS.
