Hi,
some days ago I've installed gcc-8-20180225 with accelerator support
on my "SUSE Linux Enterprise Server 12.3 (x86_64)" with gcc-6.4.0.
Yesterday I tried to add the languages objc, obj-c++, and go to my
installation. Unfortunately, I lost the OpenMP support. Adding the
languages step-by-step, I found out that "go" is responsible for the
problem.

The commands to build both versions are only different for the language
part.

I used the following commands to build everything.

Using "make" instead of "make -j 6" didn't change the result. Does anybody
know why "go" prohibts a correct build process for OpenMP? Do you need
any files from my build-directories to investigate the problem? I would be
grateful, if somebody knows a solution or can fix the problem. Thank you
very much for any help in advance.
Kind regards
Siegmar
