scallywag zp_texlive_finish.dash failing exit code 2 rebuilding installed formats

[Brian Inglis]

Any way to see if there is anything useful in scallywag #160 (3181) 
fontconfig run 1154600337 build_requires setup /var/log/setup.log.full 
without hacking and pushing fontconfig.cygport?

https://github.com/cygwin/scallywag/actions/runs/1154600337/workflow

Trying to build updated fontconfig (to see if continual cache creation 
issue has been resolved, or analyze and hopefully debug that issue to 
remove or patch the cause, then ITA), but getting weird build issues.

Trying scallywag playground, but it's also having problems installing 
prereq texlive-collection-htmlxml, which pulls in other packages 
including texlive-collection-formatsextra, which need built by
/etc/postinstall/zp_texlive_finish.dash, which is failing somewhere with 
exit code 2 - not a lot of detail!
