mconf make me annoying I have to make menuconfig && exit to save
the config when I am tuning .config time by time, it is even
worse I have to search down to my desire submenu time by time.
So I add "Save" button to save our time. With "Save" button,
I can use CRTL-Z after save config, and then use "%" or fg to
resume menuconfig and go on tuning.
