Collapse the arch,os-specific directories into the main directory by renaming xxx/foo.c to foo_xxx.c, and so on. There are no substantial edits here, except to the Makefile. The assumption is that the Go tool will #define GOOS_darwin and GOARCH_amd64 and will make any file named something like signals_darwin.h available as signals_GOOS.h during the build. This replaces what used to be done with -I$(GOOS). There is still work to be done to make runtime build with standard tools, but this is a big step. After this we will have to write a script to generate all the generated files so they can be checked in (instead of generated during the build).
