configure: clean up use of extra_ldflags and libs_mplayer

Now, extra_ldflags ought to only consider LDFLAGS, and all libraries
shall go into libs_mplayer. In the end, the command line first contains
extra_ldflags, and then libs_mplayer.

So altogether this change has the effect that libraries get added to the
linker command line in the order the configure script checks them.
Previously there was some reordering due to some checks adding libraries
to libs_mplayer and some to extra_ldflags.
