stage2: skip recursion test on some hosts

Browse Source 
In order for this test to pass, the host linking/start code needs to
support explicitly setting the stack size. Zig defaults to 16 MiB stack
size, which is enough to pass the test in Debug builds, however, most
operating systems do not honor the stack size we request for and give a
smaller amount.

Eventually the goal is to pass this test on all hosts.
