Cross‐compiling for Linux from macOS ARM64

I do some development on an M1 MacBook, and since adding SQLite support we also needed to start building with CGO_ENABLED=1 which causes some issues when cross-compiling to Linux.

A work around in to install musl-cross:

brew install FiloSottile/musl-cross/musl-cross

And then compile with:

CC=x86_64-linux-musl-gcc CXX=x86_64-linux-musl-g++ GOARCH=amd64 GOOS=linux CGO_ENABLED=1 go build -ldflags "-linkmode external -extldflags -static"

This will allow you to build the binary for Linux amd64 on your Mac with an M1 o rM2 processor.
