Subject[RFC PATCH 1/3] kbuild: generate *.hash.c during build
Date
*.hash.c files are artifacts generated from *.gperf by using gperf.
Instead of running gperf, we conventionally version-control
*.hash.c_shipped files and copy them to *.hash.c during build.

It is true that this approach can minimize external tool dependency,
but we need to update the shipped files from time to time. This
commit switches to build-time generation of the intermediate C files.
