Ingo Weinhold 18ca835d6d Merged in the changes to version 4.1.2.
* Solved conflicts with the libtool related files by simply using the
  vendor versions. IIRC the haiku related changes to libtool and
  autoconf were relevant only for the binutils.
* Solved {libstdc++-v3,libmudflap}/configure conflicts by re-running
  autoconf for these directories.

I'm already working on fixing the Haiku build, so please don't do the
same.
