#
# Shell script to build multiple directories
#
DIRS="dir1 dir2 dir3 dir4 ..."
#
# To find all the directories in the cwd, one could also:
# DIRS=$(ls -l | sed -e '/^d/!d' | awk '{print $8;}')
#

for dir in ${DIRS} ; do {
	# run each build in its own shell to return to this dir.
	# if any command within the sub-shell fails, this shell
	# should also exit
	( cd $dir ; \
	./autogen.sh && \
	make && \
	su --command="make install" - ) \
	|| exit 1
done

Hope this helps.

Enjoy,
