AW: Building PosgresSQL with LLVM fails on Solaris 11.4

Hi Andres

Thanks a lot.
It now got much further but failed here with Sun Studio:
…

gmake -C backend/jit/llvm all

gmake: *** [GNUmakefile:11: all-src-recurse] Error 2

With ggc it fails at the same step as before.
I have attached the log files of the SunStudio and gcc runs to the email.

Many thanks for your help.

Best regards
Sacha

That's me making a silly mistake... I've attached at an updated, but still
blindly written, diff.

Could you attach config.log and gmake for the gcc based build? Because so far
I have no idea what causes the linker issue there.
