tools: Connect to the kernel build system
Now you can do
$ make tools/<toolname>
from the toplevel kernel directory and have the respective tool built.
If you want to build and install it, do
$ make tools/<toolname>_install
$ make tools/<toolname>_clean
should clean the respective tool directories.
If you want to clean all in tools, simply do
$ make tools/clean
Also, if you want to get what the possible targets are, simply calling
$ make tools/
should give you the short help.
$ make tools/install
installs all tools, of course. Doh.
