games-board/stockfish: fix clang build failure

COMP should be a fixed string like clang/gcc to set tools for PGO.
Possible values are described in https://disservin.github.io/stockfish-docs/stockfish-wiki/Compiling-from-source.html#compilers
Note that even though COMP points to C compiler, stockfish calls only C++ compile provided in COMPILER parameter.
