<pre>
`LIBOMPTARGET_ALL_PLUGIN_TARGETS` is initialized to include amdgpu, cuda and host. Then amdgpu and cuda are automatically disabled on non-x86/aarch64/ppc64 platforms, such as s390x. But lateron we assume that all plugins in LIBOMPTARGET_ALL_PLUGIN_TARGETS exist and link against them, resulting in linker errors like the following:

This used to work before offload was separate from openmp.
Either the build system should make it a hard error to specify a plugin that can't be build (in which case the user has to explicitly adjust `LIBOMPTARGET_ALL_PLUGIN_TARGETS`), or it should not try link plugins that it did not build.
