🚀 Feature Request

Relevant Package [REQUIRED]

All golang components.

Description [REQUIRED]

A number of new security flags have been added to golang that should be integrated into our makefiles.

For binaries that interact with legacy C libraries, we should enable address sanitization, -msan -asan :
golang/go#44853

There are also flags to mitigate against speculative execution attacks, -spectre=index,ret

Potentially, can do this:
GOFLAGS=-trimpath -mod=readonly -asmflags=all="-spectre=all" -gcflags=all="-spectre=all" -ldflags="-s -w"
