hidden symbol __cpu_model is referenced by DSO

I am running 8.2.0 on linux, and I see this same problem with a basic
hello world:

$ cat a.f90
program hello
print *, "hello"
end program

$ gfortran a.f90
/opt/gcc/bin/../lib/gcc/x86_64-pc-linux-gnu/8.2.0/../../../../x86_64-pc-linux-gnu/bin/ld:
a.out: hidden symbol `__cpu_model' in
/opt/gcc/bin/../lib/gcc/x86_64-pc-linux-gnu/8.2.0/libgcc.a(cpuinfo.o)
is referenced by DSO
/opt/gcc/bin/../lib/gcc/x86_64-pc-linux-gnu/8.2.0/../../../../x86_64-pc-linux-gnu/bin/ld:
final link failed: Bad value
collect2: error: ld returned 1 exit status


Any idea how to go about troubleshooting this?

I've had a look at the PR, and it seems there is some problem
about shared / non-shared values of __cpu_model.

I think your best bet would be to re-open the PR and add the
appropriate info there - how you configured your compiler,
output of gfortran -v, etc.

One think that you could try as a workaround would be to
specify -static-libgcc.
