Now that we no longer modify the user's $GOROOT and run make.bash,
the need for isolating the environment is gone. Pass through
whatever users want, overriding only those necesssary for corss
compilation.
While here, remove some dead code.
Fixesgolang/go#11672.

The goal here is to remove several inconsistencies between
-target=android and -target=ios support, along with making the flow
of the command follow the path you might expect given a certain set
of flags, and preparing for `gomobile bind` support of ios. In
particular, building non-main packages now works with both targets
and the initialization of global build state is clearer.
The reorg also is designed around an nm trick I thought of
yesterday to do better package import scanning without a slow
all-file scan. This will give better detection of x/mobile/app and
x/mobile/exp/audio/al packages. There's a TODO about it, and I'll do
it in a future CL.
Tested with:
go test golang.org/x/mobile/cmd/gomobile
gomobile init
gomobile bind golang.org/x/mobile/asset
go test golang.org/x/mobile/bind/java
gomobile build -target=ios golang.org/x/mobile/example/basic
gomobile build -target=ios golang.org/x/mobile/gl
gomobile build -target=android golang.org/x/mobile/gl
gomobile build -target=android golang.org/x/mobile/example/basic
(Along with manual testing of basic on an android device.)
That might make a pretty good _test.go.

The Go toolchain used to require that we rebuild the compiler and
friends (the cgo command) when building a cgo-enabled cross compiler.
This meant that gomobile init used to invoke make.bash in a temporary
copy of the GOROOT. This works, but brings with it several
complications, including needing to use -toolexec when invoking the
go tool, finding a boostrap copy of Go 1.4, long initialization
times, and a variety of unusual failure modes.
Fortunately we don't need our own compiler any more. All that's
necessary is building the standard library for the cross-compilation
targets and making sure the right C compiler is used when calling
go build (as it always was). This means most of the initialization
process can be replaced with a carefully invoked 'go install std'.
While here, remove the source install instructions (most of it is
documented already, and the final step, choosing the right git
revision should be within the skills of anyone using pre-release
software.) Some other documentation is changing because it's been a
while since go generate was run.

Also add a very simple test for gomobile build, some
documentation cleanup, and the -o flag for bind.
