Browse Source 
- 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

  gitlab: work harder to avoid false positives in checkpatch
  tests/acceptance: tag various arm tests as TCG only
  tests/tcg/configure.sh: tweak quoting of target_compiler
  meson.build: fix cosmetics of compiler display
  tests/tcg: add a multiarch signals test to stress test signal delivery
