The build chroots there have postgresql-NN already installed so
extension builds don't have to download 7 PG versions over and over.
My guess would be that that's the difference and it's using some
pg_config from /usr/bin or /usr/lib/postgresql/*/bin.
I can confirm that it's also failing in my local chroots if none of
the postgresql-* packages are preinstalled.
