Looking to dissect kbuild

[Eric Fowler]

I have been building bespoke ucLinux kernels by way of 'make menuconfig'
and running into various problems. I know I need to edit my dot-config file
to set build flags but I am having to do too much tweak-and-try.

I want to know more about how that file interacts with the build system. In
particular, in situations like a build seeing a syntax error in foo.c, I
want to trace from foo.c all the way up to every entry in dot-config that
imports or depends on foo.c.

Basically I am looking for high level architectural help / debug guide on
kbuild.

Where would I find such a resource? My google searches have not turned up
much.
