This is where the noobish step was taken.
Boardconfig is meant to be constructed from scratch by analyzing the kernel configuration(Don't keep on shooting device specs are same)
Device specs doesn't mean you can grab the device configuration from it.
The location from where the source is synced doesn't matter(provided that its unmodded) but the Configuration matters a lot. Compiler analyses the configuration and readily modifies the source code and initializes compilation.
And this is why major functions are not working in your buid.
I saw your github repo of A60 and as it is a initial commit I cannot see what configurations you changed.
Can you mention here the modified lines?
And for "you need to learn more than me"
I would say no one is perfect, I agree that I have no experience in building a ROM from source(as I lack a good network connection) but that doesn't mean I have no knowledge in it. And for that statement you may receive a infraction from a XDA moderator
These are fundamental aspects which are needed to be understood before proceeding with a build.
