kconfig/conf: fix randconfig setting multiple symbols in a choice
Currently, randconfig may set more than one symbol in a given choice. Given this config file: config A bool "A" if A choice bool "B/C/D" config B bool "B" config C bool "C" config D bool "D" endchoice endif # A Then randconfig generates such .config files (case where A is not set is not shown below for brevity), and where only the right-most .config is valid: CONFIG_A=y CONFIG_A=y CONFIG_A=y CONFIG_B=y CONFIG_B=y CONFIG_B=y CONFIG_C=y # CONFIG_C is not set # CONFIG_C is not set # CONFIG_D is not set CONFIG_D=y # CONFIG_D is not set That is, in a randomised choice, the first symbol is always selected, and at most one other symbol may be selected. This is due to symbol randomised in a choice not being properly flagged as having a value. Fix that by flagging those symbols adequately: have a user-defined value, and be not valid (to force recalculation of the symbol). Note: if the choice is not conditional, then the randomisation is properly done.
