Build Notes

Previously the openblas recipe built static llbraries using the source package makefiles but the shared libraries were built in a manual step. This PR improves the building workflow by using the source package makefiles for both, by specifying the C and Fortan compiler flags a bit more carefully and adding a one-line patch to one of the makefiles to avoid the shared library building trying to link with system libraries that are not required. The result of this is that the generated shared libraries are correctly versioned and the build config files include extra information that makes building downstream libraries easier to do.
