Dear maintainers,

as you probably already know, the latest pocl 7.1-4 fails to build the debian packages on amd64 due to following error:

I managed to fix this error and successfully build the .debs by removing the mentioned line 51

(arch=amd64)_ZNKSt7__cxx1112regex_traitsIcE5valueEci at Base 7.1

from pocl/debian/libpocl2t64.symbols. I've also installed and tested the resulting packges. So far I've had no problems, however I'm not fully aware of the consequences of removing said line from the .symbols file.

Kind regards,
Christian
