Subject: [PATCH] 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.
