build error ('undefined hidden symbol') using amdclang compilers and no optimizations on frontier

[cwsmith]

Building using the amd compilers without optimizations results in compile errors:

https://github.com/SCOREC/omega_h/wiki/Build-and-Run-on-OLCF-Frontier#build-with-mpi-enabled-using-cray-compiler-wrappers-and-amd-compilers

Adding -O1 or -O2 results in a successful build.
