if you configure with  --enable-stage1-languages=all,

1) will all the libraries be built three times during bootstrap, or just
   once?
2) is it still possible to just build the stage1 compiler without the
   libraries?

thanks, the "make distclean-stage2 clean-target" actually is exactly
what I need (although I specified something different :-)
