lode's "add a mode to consider autogen.sh failure 'ok'"

[Stephan Bergmann]

Anybody remember what the lode repo's 
<https://gerrit.libreoffice.org/plugins/gitiles/lode/+/1d0e18c1ce4bf703efe1266db6ce692ae0e4bafd%5E!/> 
"add a mode to consider autogen.sh failure 'ok'" is supposed to achieve? 
  AFAICS, what it does now is consider "Random Config Linux builder" 
builds like 
<https://ci.libreoffice.org/job/lo_tb_random_config_linux/1633/> as 
successful, even thought they fail in the configure step:

[...]
> checking for gperf... /usr/bin/gperf
> checking whether gperf is new enough... configure: error: "GNU gperf 3.0.4" is too old or unrecognized, must be at least gperf 3.1
> Error running configure at ./autogen.sh line 296.
> No emails were triggered.
> Finished: SUCCESS
