[dev.regabi] cmd/go: Use GOMAXPROCS to limit default build, compile parallelism
When people want deterministic/single-process builds, they probably
assume that GOMAXPROCS=1 will do that. It currently does not,
neither for build parallelism nor for compiler internal parallelism.
(Current incantation for that is "go build -p=1 -gcflags=all=-c=1 ... ")
This CL makes
"GOMAXPROCS=1 go build ..."
behave like
"go build -p=1 -gcflags=all=-c=1 ... "
RELNOTE=yes
