Change Details

There are two things to investigate here: 1) How does GN track header files when building Hafnium, i.e. does a change in a header file trigger rebuild of all source files that include it? 2) We've seen the build system not recompile the Linux driver after a change to one of Hafnium's header files (inc/vmapi/hf/*). 2a) `make` needs to rebuild the driver if a header file changes 2b) GN needs to run `make` on the driver if a header file changes (Migrated from b/141459219.)
