[NSWI004] memset missing reference

[Petr Tuma]

Hi,

in some situations, GCC generates code that assumes `memset` is 
available (from the doc: GCC requires the freestanding environment 
provide memcpy, memmove, memset and memcmp).

Probably the easiest workaround is to implement `memset` yourself, since 
there is no need to make it super efficient it should be trivial.
