 If we want to use gcov in RTEMS to get code coverage in all system states,
 then we need some tweaks in GCC:

 The linker set based gcov information registration is already included in
 GCC:

 fprofile-info-section

 There is a discussion about how the gcov information can be transferred
 from the embedded system to the host:

 The GCC integration needs to wait for the GCC 12 development start.
