This regex decides whether to use O3 opimisation on numpy or not. It includes "od", which happens to be a substring of "reproducible" but not "qemux86-world". The regex will run against all compiler options including things like: -fmacro-prefix-map=/XXX/build/tmp/work/core2-64-poky-linux/python3-numpy/1.26.0/numpy-1.26.0=/usr/src/debug/python3-numpy/1.26.0-r0 i.e. including build paths. Reduce the regex to something deterministic for our builds, assuming nobody builds in /home/debug:full/ The autobuilder race depended upon whether qemux86-world or the reproducible target ran first and won the race to populate sstate.
