(cherry picked from commit 94e08f7)

During the refactor we forgot one more place where the `flag_values` on
the platform information was used. They were no longer populated and
broke.

The solution is to use `selects.config_setting_group` to maintain
behaviour and in order to smoke test I have added a target to verify
that the aliases work.

(cherry picked from commit 107a878)

The `exec -a` command doesn't work in dash, the default shell for
Ubuntu/debian.

To work around, use `sh -c`, which is posix and dash compatible. This
allows changing
the argv0 while invoking a different command. Also adds a test to verify
the the
runtime_env toolchain works with bootstrap script.

Fixes #3009

(cherry picked from commit c4543cd)

It seems that the only function that did not have unit tests have bugs
and the integration tests did not catch it because we weren't creating
namespacepkg `__init__.py` files.

This change fixes the bug, adds a unit test for the remaining untested
function.

…enabled (#3031)

There's a bug in the version string parser that doesn't handle local
identifiers correctly.

Thankfully, it's only activated in the experimental code path when site
packages for
libraries is eanbled. Moving the logic within that block works around
it.

Work around for
#3030

(cherry picked from commit aab2650)

…es are disabled (#3059)

The refactoring to move the pkgutil shim generation to build phase
inverted
the logic for when it should be activated. When
`enable_implicit_namespace_pkgs=True`, it means to not generate the
pkgutil shims
("respect the Python definition of the namespace package").

To fix, just invert the logic that activates it.

A test will be added in a subsequent PR because the necessary helper
isn't
in the 1.5 branch.

Fixes #3038
