e80edfc7bf cleanup Makefile.inc and fixed mergeconfig
Remove the environment file due the fact it was destructive and
removed existing .config and build environment. Now, if you change
the architecture, you will not be building against old environment,
instead, kconfig will prompt you for the changes.

specific CFLAGS by using the Makefile and Kbuild combination
in the arch/<arch> directory.

This will also allow adding architecture specific targets and is
easy to maintain when alongside the architecture.

Using nm and sed works fine on Linux, however when moving to other
platforms, nm and sed do not work the same way and might have
different behaviour. This reduces dependency on host tools and brings
back the code for generating the offsets.h directly using a built
utility that is portable.
