headless build fails

[umlaeute]

i'm currently trying to build gmerlin in a headless environment (using Docker).

After working around #7 (by removing the offending line), my build fails with:

$ make

(re-running make succeeds for whatever reasons!)

it would be great if the build succeeded the first time, even if it's impossible to "open display".

I don't really see, why -help-man would actually attempt to create a window in the first place.

I completely kicked out the manpage generation from the build process, so this issue should be fixed.

The X11 error was a nasty artefact from the X11 plugin being loaded by the initialisation of the plugin registry.
