Added symbolic link to install a generic blas library that can be used by
Octave and R.
+OpenBLAS has cpu specific targetted assembly code for speed optimisation.
+If running in a vm with QEMU cpu you need to specify a variable
+TARGET=cpuname to the script where cpuname is one from the list in the
+sourcecode file TargetList.txt
+examples are TARGET=NEHALEM for an Intel i7 or TARGET=ATHLON for AMD Athlon
