I'm pretty sure we want runtime relocation of upstream symbols.
On Linux I had to link against Lucy.so. Otherwise I get "undefined
symbol" errors when running the tests.
There seem to be two workarounds on Linux: Link the main executable with
-rdynamic or pass the RTLD_GLOBAL flag to dl_open. Since our main
executable is perl, the former won't work. But the latter can be
achieved by using DynaLoader with dl_load_flags set to 1.
