* Ensure that when building gcc, libstdc++ is linked against the

libgcc of the gcc being built, not the gcc building it.
* Only include a directory in the rpath of an executable/library if it
  is actually used.  Before, the `/lib' directory of every build input
  was added to the rpath, causing many unnecessary retained
  dependencies.  For instance, Perl has a `/lib' directory, but most
  applications whose build process uses Perl don't actually link
  against Perl.  (Also added a test for this.)
* After building glibc, remove glibcbug, to prevent a retained
  dependency on gcc.
* Add a newline after `building X' in GNU Make.
