Thanks for spotting that. The problem turned out me being not smart
enough to determine the newest llvm version installed; the
not-quite-correct Makefile code failed on "9" < "10".

I have now fixed that problem. Updated postgresql-{11,12,13,14}
packages using libllvm10 instead of libllvm9 are available in
focal-pgdg-testing.

Since this is potentially a breaking change, I'll not push these live
immediately but will give people a chance to test these until next
week.
