[IRCServices] Dynamic modules support in 5.0.x

[Robin Burchell]

Hi,

It appears configure doesn't correctly detect dlopen support on some
systems (x86_64/amd64 3200+ Gentoo w/gcc 4.1.1 at least) - because it
does not compile test-dlopen.c with -fPIC.

Passing -cflags -fPIC to ./configure  fixes the problem.

Is it possible to get configure patched to avoid this workaround?

Thanks.
