xcb + build.sh + util + demo

[Ron Wezeman]

Have build default with util/modular/build.sh when adding 'build xcb
util' above row 'build xcb demo'. Now get's the error:

gcc  -g -O2   -o hypnomoire  hypnomoire-hypnomoire.o
hypnomoire-reply_formats.o  -lm -lpthread 
hypnomoire-hypnomoire.o: In function `event_thread':
