gnome-libs fails to compile without esound installed

Hi,

I do not have a soundcard and so I don't need soundsupport in
gnome. But gnome-libs fails to compile if the esound libs are nor
installed. 

gcc -g -O2 -Wall -Wno-unused -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -o .libs/gnome-dump-metadata -L/usr/local/lib -lglib gnome-dump.o -Wl,--rpath -Wl,/opt/gnome/lib .libs/libgnome.so -L/usr/local/lib -lglib -lm -ldl -lm -Wl,--rpath -Wl,/opt/gnome/lib ../support/.libs/libgnomesupport.so -lm -ldb -L/usr/local/lib -lglib -ldl -lm
