Fix Apple clang PCH compile error with -o flag (#7251) (#7327) 

Apple clang rejects `-o` when a precompiled header (.gch) is involved,
reporting "cannot specify -o when generating multiple output files".
Remove the unnecessary `-o $@` from the two PCH build rules; the
`%.o: %.cpp` pattern already implies the correct output name.
