Libreoffice error during autogen

where it IMO fits better; please try to avoid private mails:]

Seeing that that change passed Jenkins, I naively assumed that 
libclangSupport would generally be available with our compiler plugins 
Clang 12.0.1 baseline (even if I myself only checked that change with my 
local LLVM 16 trunk build).

Please look into your config.log, why exactly "checking for clang 
libraries to use" fails for you.
