go/packages: initialize config.Env with os.Environ when unset

This makes Load use the value of GOPACKAGESDRIVER in the current
process's environment if the loader's environment wasn't explicitly
set.

Note that if GOPACKAGESDRIVER is not set, we'll still search PATH in
the current process, regardless of whether PATH is set in the loader's
environment. This has not changed.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
