That is actually only a work-around. Pkg-config can handle the difference 
between static linking and dynamic linking but you have to tell it what is 
what. However, not all upstream developers that emit pkg-config files make 
proper use of that.

OTOH, some APIs import types from other libraries so that linking to those is 
necessary to avoid problems when upgrading. That's where -Wl,--as-needed is 
not the proper solution (as the linker cannot know this).
