What about installed headers and libraries that don't go in versioned
directories?  $(PREFIX)/include/g++-v3/*, $(PREFIX)/lib/libgcc_s.so, etc?

I'd argue that header files should probably move under
$(PREFIX)/gcc-lib/$(TARGET)/$(VERSION)/, but doing that for shared libraries
is a lot more troublesome.
