resolves #170 build v8go for musl libc

[ggrossetie]

What I Did

• create a new workflow to build GN on Alpine (build dependency of v8)
  • it will automatically create a pull request
  • if you don't trust the compiled file available at deps/alpine_x84_64/gn, you can run the workflow again to replace this file
• add a new workflow to build v8 on Alpine
  • get v8 dependencies from the GitHub runner (ubuntu-20.04) because the script does not work on Alpine
  • use Docker to build v8 on Alpine
  • copy files from the Docker container and create a pull request
• introduce two Python scripts to split the build task since we cannot get v8 dependencies from Alpine
  • get_v8deps.py : get v8 dependencies
  • compile_v8.py : compile v8
  • build.py uses functions from the get_v8deps.py and compile_v8.py scripts to get dependencies and compile v8 (in one go)
• add cgo directive for deps/alpine_x86_64 (disclaimer: I don't know what I'm doing 🐶)
  • as far as I understand, it would allow to pass an environment variable CC=musl-gcc to install v8go on Alpine?
• create a module deps/alpine_x84_64/vendor.go

resolves #170

Note : I'm currently building libv8.a for Alpine on my fork

[ggrossetie]

I've added deps/alpine_x86_64/libv8.a. How can I test that everything is running fine on Alpine?

[ggrossetie]

Yay! tests are running fine on Alpine 🎉
I'm using a Docker container to run the test + coverage on Go 1.17.13 alpine3.16 and 1.19.3 alpine3.16.

You can see the result on my fork: https://github.com/Mogztter/v8go/pull/1

Will this fix 32 bit arm too? Or is there perhaps a way to put the build workflow in the process, so don't need to pre-vendor?

[ggrossetie]

Not really but you can use the same approach to compile V8 on arm32 using Docker.

@ggrossetie Hi there! The link for the result is not working. Could you please share the working example?

I was trying to build a native binary for D2 but they are now using another library so I've deleted my fork 😞
