Russ Cox 5993251c01 cmd/go: implement per-package asmflags, gcflags, ldflags, gccgoflags
It has always been problematic that there was no way to specify
tool flags that applied only to the build of certain packages;
it was only to specify flags for all packages being built.
The usual workaround was to install all dependencies of something,
then build just that one thing with different flags. Since the
dependencies appeared to be up-to-date, they were not rebuilt
with the different flags. The new content-based staleness
(up-to-date) checks see through this trick, because they detect
changes in flags. This forces us to address the underlying problem
of providing a way to specify per-package flags.

The solution is to allow -gcflags=pattern=flags, which means
that flags apply to packages matching pattern, in addition to the
usual -gcflags=flags, which is now redefined to apply only to
the packages named on the command line.

See #22527 for discussion and rationale.

Fixes #22527.

runtime/race package contains the data race detector runtime library.
It is based on ThreadSanitizer race detector, that is currently a part of
the LLVM project (http://llvm.org/git/compiler-rt.git).

To update the .syso files use golang.org/x/build/cmd/racebuild.

Current runtime is built on rev 68e1532492f9b3fce0e9024f3c31411105965b11.
