#     Makefile: add comment to discourage tools/* addition for kernel builds
#     
#     Kbuild provides scripts/Makefile.host to build host programs used for
#     building the kernel. Unfortunately, there are two exceptions that opt
#     out of Kbuild. The build system under tools/ is a cheesy replica, and
#     cause issues. I was recently poked about a problem in the tools build
#     system, which I do not maintain (and nobody maintains). [1]
#     
#     Without a comment, people might believe this is the right location
#     because that is where objtool lives, even if a more robust Kbuild
#     syntax satisfies their needs. [2]
