Ouch! :-)  I don't think I have enough familiarity with multilibs and 
the like to split libgcc into its own toplevel directory...  It is not 
like libcpp and fixincludes, surely.  Not to mention modifications to 
the GCC driver that are probably needed for that.

Surely moving libgcc to the toplevel would be a worthwhile goal on its 
own, and would enable in turn moving multilibbing to the toplevel which 
is another favorite cleanup of mine.  But while toplevel bootstrap could 
be a first step in that direction, you'd have *target* bootstrapped 
modules which are not yet supported.

My plans for configury work in 4.1 mostly involved the creation of a 
common aclocal library in the toplevel's config directory, also to 
remove the hack whereby fixincludes just uses gcc's aclocal.m4 file.
