Description: Use Debian package for BLAS/LAPACK (instead of obsolete clapack)
 - Use -lblas instead of -lblaswr
 - Use -ltmglib instead of -ltmg
 - Do not use f2c, not needed
 - Introduce prototypes for LAPACK functions used in the package
   (those are documented in the manpages from the liblapack-doc package)
