in Settings->Compiler and Debugger...:Global compiler settings
In linker settings, you may have the -s option (which is for stripping symbol with gcc)
In ToolChain executables, you should NOT have gcov anywhere.
(values would be :"gcc, g++, g++, ar, gdb, windres, make" (with possible prefix like mingw32-) for gcc compiler).
gcov is a program which tell you which part of your code has been executed,
it is neither a compiler nor a linker.
