Similiar to ELPA_2011.12 this version of ELPA now supports automake.

To the _source_ code of ELPA the following changes had to be made:

-elpa2.F90 now use the create "config-f90.h" file to choose via
 preprocessor switches which kernel was defined by the user

- the SSE-AVX intrinsic kernels of A. Heinecke had to be changed such
  that they support "internal linkage" for the building of a shared
  library.

The following other changes were made to the documentation

- elpa2_kernels/README_elpa2_kernels.txt was updated; the new configure
  targets are explained

- README, INSTALL were updated

To high propability this commit is the last one, before this beta
version	will become an official release
