Subject: add clapack files

Adding two files that are part of clapack source
The clapack archive that can be downloaded at
  http://www.netlib.org/clapack/
contains a copy of f2c.  This copy copy is basically identical but it includes
two files which are missing in the source which was the base for the libf2c2
package.  Since the functions inside these files are used inside the test suite
of clapack the files were added here to avoid code duplication.

Add missing files also to makefile.u to get them built
