Subject[PATCH 4/4] gcov: clang: pick GCC vs Clang format depending on compiler
Date
Clang gcov format is only supported by Clang compiler, and Clang
compiler only supports Clang format.

We set gcov format to depend on which compiler (GCC or Clang) is used.

Automatic format detection behavior is preserved because:
If GCC is used, one of the GCC gcov formats is selected.
If Clang is used, Clang gcov format is selected.
