testsuite: Add _link flavor for several arm_arch* and arm* effective-targets

For arm targets, we generate many effective-targets with
check_effective_target_FUNC_multilib and
check_effective_target_arm_arch_FUNC_multilib which check if we can
link and execute a simple program with a given set of flags/multilibs.

In some cases however, it's possible to link but not to execute a
program, so this patch adds similar _link effective-targets which only
check if link succeeds.

The patch does not uupdate the documentation as it already lacks the
numerous existing related effective-targets.
