Kindle requires an ARM 32-bit build.
I don't know Go, but a quick check locally shows:
Code:
go tool dist list | grep linux
linux/386
linux/amd64
linux/arm
linux/arm64
linux/loong64
linux/mips
linux/mips64
linux/mips64le
linux/mipsle
linux/ppc64
linux/ppc64le
linux/riscv64
linux/s390x
The only one that might work is arm.
