      This fixes PR gcov-profile/54487 where the gcda files were not locked
      by the profile-use read, enabling writes by other instrumented compiles
      to change the profile in the middle of the profile use read. The GCOV_LOCKED
      macro was not set because it was guarded by HOST_HAS_F_SETLKW, which was
      never set. The fix is to add a compile test in the configure to set it.
