Hmm, that will however affect runtime as well, which I'd rather avoid.

Basically, I'd like to have a diagnostic when a symbol is missing while
linking a plugin, but accept those symbols as missing that will be
provided by the program later on. The plugins need to be linked before
the program though, so they are available for -dlpreopen if the user
decides to link statically.

The plugin should still fail to load if dlopen()ed by anything that
doesn't provide the symbol.
