[Buildroot] [PATCH 1/1] package/pistache: link with libatomic when needed

[Fabrice Fontaine]

pistache does not mandatory link with libatomic since
https://github.com/oktal/pistache/commit/4ed3f8e148dae203730139ae3c1c4c87bfc86c02
however the logic is broken due to an unknown issue in CheckAtomic.cmake.

Instead of trying to fix it, just link with -latomic if needed

Fixes:
