[fixed]gcc 4.6 no longer recognizes some linker options

Building irr fails on the latest stable gcc. Debian patch is to remove this line:
staticlib sharedlib: LDFLAGS += --no-export-all-symbols --add-stdcall-alias

I think the proper fix would be to prefix it with -Wl,
Gonna read some more about these options and fix it int he makefiles. Should work even with older gcc versions, so no problem to change it globally.

No, the linker won't accept those options either, I tried that. edit: the --no option seems to have disappeared, and the --enable one is renamed --add, and is only effective on mingw. It errors out on native linux.

Ok, the std-call option is windows anyway. Don't know why it wasn't put there. the export of symbols needs to be checked some further. Would be best to have this properly closed down on all systems. As far as I see, we already have the gcc attributes properly set for gcc4 systems, so you simply need to add -fvisibility=hidden to the CXXFLAGS. Since we don't have a configuration process, though, we cannot make this automatic. So please add this parameter manually while we support gcc3 as well.
