This includes a number of changes:

- ScaLAPACK2 on from the openSUSE:science repository is now correctly
  auto-detected. As ScaLAPACK2 already includes BLACS, an additional
  BLACS library must not be linked!

- The resulting library is now called elpa-2014.06.000.so, as was
  probably originally intended anyway

- The pkg-config file was renamed to elpa-2014.06.000.pc and filled with
  correct values. With this, a package using ELPA can easily get the
  necessary compilation and library flags.

In this commit, only the "precious" files (Makefile.am, configure.ac,
etc.) are included, to make clear what has been changed by hand.

In the subsequent commit also all autoconf generated files will follow.
