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.
