Error when linking 
Hi,

I just pulled the FEX sources and tried to build them, according to the instructions in https://github.com/FEX-Emu/FEX#quick-start-guide.

The build gets me in the error listed below when linking UnitTestGenerator. I would appreciate some tips on getting past this.

Some details:

clang version 10.0.0-4ubuntu1 
Target: aarch64-unknown-linux-gnu
Linux version 5.10.87
Description:    Ubuntu 20.04.4 LTS

Thanks,

Julius
