This fixes an undefined symbol error happening when compiling
the server with the --disable-xv configure switch.
Basically, xnest was linking against
@XSERVER_LIBS@ and @XNEST_LIBS@ and the order of the libraries
given to the linker at the end of the process was bogus.
* configure.ac: make XNEST_LIBS contain the $XSERVER_LIBS re-ordered
in such a way that the linker finds the symbols of all the libs contained
in $XNEST_LIBS.
* hw/xnest/Makefile.am: don't link against @XSERVER_LIBS@ anymore because
XNEST_LIBS contains the right thing.
