The one new assembly source file, `arm/adddf3.S`, implements both addition and subtraction via cross-branching after flipping signs, since both operations must provide substantially the same logic. The new cmake properties introduced in a prior commit are used to arrange that including `adddf3.S` supersedes the C versions of both addition and subtraction, and also informs the test suite that both functions are available to test.
