test program

It's not possible to write shared plugins in ada because libgnat (and only
libgnat from gcc) is built with nodlopen option.

Example:
Error: unable to load plugin "~/.weechat/plugins/liblibaweeplug.so":
libgnat-4.9.so: shared object cannot be dlopen()ed

How to reproduce:
Try to dlopen libgnat.so. dlopen returns NULL works fine for libc/libm/etc
