[BUG] rv-virt/citest: test_hello or test_pipe failed

[lupyuen]

Description / Steps to reproduce the issue

Since yesterday: rv-virt/citest has been failing test_hello onwards, or test_pipe onwards, hanging our CI Checks in GitHub and Build Farm. It might have been caused by one of these NuttX Commits:

• arch/toochain: Add toochain to gcc
• mps3-an547:ap: Disable cmd_wait() as it depends on procfs currently
• Earlier commits were OK

Or maybe one of these NuttX Apps Commits:

• nshlib/pipeline: Concat variable arguments failed
• nshlib/nsh_parse: Fix variable arguments concat error of nsh_execute()
• Earlier commits were OK

Also when one test fails: Why do the rest of the tests take a loooong time to fail, hanging our CI Checks in GitHub and Build Farm?
