poppler fails to build on 10.6 for undefined symbols 32bit intel

[rmottola (Riccardo)]

building with clang 16 fails to link on 10.6 32bit MacBook Pro (I don't see this issue on my 64bit MacBook though).

clang: warning: argument unused during compilation: '-nostdinc++' [-Wunused-command-line-argument]

I retry, I get the same error, clang 16... I had no particular issues on 64bit.. so i though. But there I pinned version 23.11 this is version 24!
