tools build: Add detected config support
Adding support to include detected configuration makefile into the build
process. This will allow the Build objects to be configurable based on
the config data, like:
perf-$(CONFIG_KRAVA) += krava.o
The configuration is stored in '.config-detected' file, which is
generated for each compilation.
