Changeset 36c9c7810f14 broke support for grsec-patched kernels.
Those do not give back the address requested without MAP_FIXED,
so when verifying an mmap without this flag for success, the
resulting address must not be compared against the requested
address since it may have succeeded at a different location.

Apparently some distros don't let you ptrace attach
to your own existing processes.

Run strace on the child directly, instead, which
reportedly is more often allowed, and makes the
code simpler too.

Before this, make.bash --dist-tool would fail,

- if a package path leads to subdirectories only,
  show command instead, if any
- to force documentation for a command, use the
  cmd/ prefix, as in: godoc cmd/go
  (note that for the go command, the prefix is
  not required since there is no actual go library
  package at the moment)

Fixes #3012.

* add -work option to save temporary files (Fixes issue 2980)
* fix go test -i to work with cgo packages (Fixes issue 2936)
* do not overwrite/remove empty directories or non-object
  files during build (Fixes issue 2829)
* remove package main vs package non-main heuristic:
  a directory must contain only one package (Fixes issue 2864)
* to make last item workable, ignore +build tags for files
  named on command line: go build x.go builds x.go even
  if it says // +build ignore.
* add // +build ignore tags to helper programs
