I am working to build a Kconfig based configuration menu and I need to
include a prefix variable
to source command. How do I do this? Kconfig-language.txt doesn't
explain this. Your
response will be highly appreciated...
Not supported today.
I recall I did this some time ago but that patch is long gone.
It is trivially to add.
Found my old patch...
It is one year old or more so may not apply cleanly.
