Merge remote-tracking branch 'remotes/stsquad/tags/pull-testing-updates-070621-2' into staging

A few testing and configure updates:

- add the multiarch signals stress test
- fix display of multi-word compiler stanzas in meson
- fix quoting of multi-word compiler stazas in configure.sh
- tag some acceptance tests as TCG only
- make checkpatch test work harder to find clean diffs
- split gprof/gconv job to avoid timeouts
- fix centos8 VM build by adding --source-path
- make checkpatch aware of .h.inc and .c.inc paths

tests/tcg: add a multiarch signals test to stress test signal delivery

This adds a simple signal test that combines the POSIX timer_create
with signal delivery across multiple threads. The aim is to provide a
bit more of a stress test to flush out signal handling issues for
easily than the occasional random crash we sometimes see in linux-test
or threadcount.
