Error when installing @jazzer.js/core on linux arm architectures

[matthewkeil]

We using the @jazzer/core for one of our libs which is also a native module. Thanks making this module!!! We prebuild the binaries for a number of architectures and found an edge case in your build process.

Issue 1) We are attempting to prebuild our library for linux/arm64 which is not prebuilt by jasser.js/fuzzer so it attempts to build it locally. The issue is that prebuild is a devDependency.

@jazzer.js/fuzzer package.json

		"prebuild": "prebuild --runtime napi --backend cmake-js --all --strip --verbose",
		"install": "prebuild-install --runtime napi || npm run prebuild",

The installation falls back to the second case where npm run prebuild scripts runs and when it does it throws Error: prebuild not found. Likely this is because its a dev dependency. For the time being we have added prebuild as a global package in our docker container but when the build runs we came up with the second issue below.

Issue 2) Your CmakeLists.txt has a target that is not supported on linxu/arm64

set(LIBFUZZER_TARGET "clang_rt.fuzzer_no_main-x86_64")

Not sure how to handle this second part of things but wanted to also bring it to your attention.
