    grub2: pass compilation parameters more accurately
    
    In order for the grub2 boot-related code to compile normally, we have
    made many adjustments to the compilation parameters. These adjustments
    are not necessary for tools-related code. We apply these parameter
    adjustments only to the boot-related code.
