FreeBSD doesn't have libdl so Amanda 3.4.3 and 3.4.4 won't build.

The in the device-src directory unconditionally tries to include -ldl. This causes FreeBSD to fail during the build.

The problem area in device-src/ is about line 1788.

I have created a local patch to circumvent this problem and both 3.4.3 and 3.4.4 seem okay, otherwise.
