[patch] CLAPACK, Solaris bits

[Jules Bergmann]

This patch allows either the builtin lapack to use either Fortran LAPACK 
(--with-lapack=fortran-builtin) or C LAPACK (--with-lapack=builtin). 
Fortran LAPACK has slightly better performance, but it requires a 
fortran compiler to build and a libg2c library.  CLAPACK doesn't require 
a fortran compiler, and it uses libF77, which is now built by VSIPL++.

This lets us continue to use the Fortran LAPACK when building binary 
packages, while making it easier to build the library from the source 
package.

This patch also builds libF77 when using CLAPACK, which removes our 
dependency on libg2c.

This patch changes the ATLAS configure to use 'test =' instead of 'test 
=='.  Solaris was tripping up on this.

Finally, this patch moves the hypotf decl to the global namespace.  I 
will test Stefan's suggestion for leaving it in the vsip::impl::fn 
namespace to see if that works.
