Makefile: Update build for include-what-you-use

Browse Source 
This patch saves the output of the IWYU build into $(obj)/iwyu.txt. It
will also automatically adds -k to the MAKEFLAFGS when IWYU is selected,
so that the build doesn't halt after the first operation.

When IWYU is not selected, there is no change to the build.

This will allow us to create an automated IWYU build on jenkins.
