Contribution description

cppcheck errors are making merging #12558 more difficult so this PR fixes this.

Testing procedure

  • Run locally: ./dist/tools/cppcheck/check.sh no errors should appear
  • Green Murdock

Please take a closer look at 1e671ac and c2f593f,

1e671ac I'm not sure if int sig = -1 is the best initial value for sig, although shouldn't really matter since its updated in the while loop..

c2f593f is because RTT_FREQUENCY doesn't have a default value so it results in a division by 0. Maybe there is a best way than duplicating the warning.

If preferred I can squash all commits fixing same errors.

Issues/PRs references

#12558 can benefit from this.

BTW, with "Cppcheck 1.89" on my arch system, I get a lot more errors.

Or deal with it later on, I think it would be good to get rid of #12558. I could open an issue and deal with it later.

Preprocesor fails to evaluate the if condicion on L91-92 because
RTT_FREQUENCY is not defined, and therefore a division by 0 occurs.
TO avoid this replicate the RTT_FREQUENCY undefined warning.
