build: pass $GCFLAGS to compiler
For example, if you are debugging an optimization problem you can now run GCFLAGS=-N gotest This is a convention for make, not for the general build, so it may go away or be done differently in the eventual 'go' command. The plan is that people will be able to test their code for rune safety by doing GCFLAGS=-r. R=golang-dev, bradfitz, lvd CC=golang-dev https://golang.org/cl/5294042
