Right now the process for adding in new constants, errors, or syscalls for Linux is a pain and unreliable. The scripts are designed to be run on the target architecture and use the header files installed on the user's system. This makes it hard to generate files for all the architectures or to have consistency between users. See golang/go#15282. This CL fixes this issue by making all of the files for the 11 supported architectures directly from source checkouts of Linux, glibc, and bluez. This is done using Docker, the gcc cross-compilers, and qemu emulation. Previously discussed here: https://go-review.googlesource.com/c/37589/ A README.md file is also added to explain how all the parts of the build system work. In order to get the build working for all the architectures, I made some changes to the other scripts called from mkall_linux.go: - Files only used for generating linux code, moved to linux/ - linux/mksysnum.pl supports a specified CC compiler. - The generated C code in mkerrors.sh changed to avoid a warning - mkerrors.sh headers changed to fix powerpc64 bug in sys/ioctl.h - linux/types.go no longer needs to export Ptrace structs in lowercase Build instructions: - Host system needs to be x86-64 Linux - Install Docker (https://docs.docker.com/engine/installation/) - ./mkall.sh (That's it!!!)
