Source code under `newlib/newlib/newlib/libm/machine/$(ARCH)/*.c`
should be added before common source code from `../../common/*.c`.
Take `newlib/newlib/newlib/libm/machine/riscv/s_fma.c` as an
example:
```
double
fma (double x, double y, double z)
{
double result;
asm ("fmadd.d %0, %1, %2, %3" : "=f" (result) : "f" (x), "f" (y), "f" (z));
return result;
}
```
Note that the common `s_fma.c` will be included by the source file
directly. The order of adding the files to CSRCS matters here.
Although the CMake-based build system does not have the same build
problem of including the a source-file with the same in the wrong
order, this commit also changes the order of inclusion for CMake
too to keep it consistent.
