162706 – math/suitesparse port does not properly detect or link atlas

The math/suitesparse port looks for and tries to link to
 	libatlas_r.so, which is no longer installed by the math/atlas port.

Fix: According to math/atlas/pkg-descr, it is no longer necessary
	to explictly link with -latlas.  The following patch works for me:



Because the Makefiles for arpack++, arpack, blocksolve95,
	fflas-ffpack, freemat, lapack++, lapack95, lapacke, levmar,
	libtsnnls, mumps, petsc, scalapack, suitesparse, and taucs
	share similar code for selecting the desired libraryies, it
	would probably be better to move it to common location like
	ports/Mk/bsd.blas.mk that could be included in the individual
	port Makefiles to make future maintenance easier.

	Something like this (though the library selection probably
	requires more thought):
