Subject: [PATCH] Fix use of Visual Studio compiler values "-w..." or "-FS"

This was needed by a Kodi addon project and ffmpeg Windows ARM compile,
where the flag "-FS" was needed, to become AppVeyor and Jenkins
more happy and the "-w..." to prevent one warning, which was given by
config.h on every compile file.

Without comes on configure:
```bash
BEGIN ./ffconf.KEHnLLrW/test.S
    1
    2   .macro m n, y:vararg=0
    3   \n: .int \y
    4   .endm
    5   m x
END ./ffconf.KEHnLLrW/test.S
