Refactor the manual Makefiles

* Compile the quadruple precision loadtxt
* Implement "make test" to run tests and run them at the CI
* Create a static libstdlib.a library and use it in tests
* Use more modern syntax and simplify
* Pass in the FC/FCFLAGS variables automatically
* Consolidate stdlib tests targets
