Subject: [PATCH 1/3] tools/vm: fix Makefile multi-targets

Build all of the $(TARGETS), not just the first one.

Without the patch (make -n)
==============================

make -C ../lib/api
gcc -Wall -Wextra -I../lib/ -o page-types page-types.c ...

Only 'page-types' target was built.

With the patch (make -n)
===========================

make -C ../lib/api
gcc -Wall -Wextra -O2 -I../lib/ -o page-types page-types.c ...
gcc -Wall -Wextra -O2 -I../lib/ -o slabinfo slabinfo.c ...
gcc -Wall -Wextra -O2 -I../lib/ -o page_owner_sort page_owner_sort.c ...

All 3 targets ('page-types', 'slabinfo', 'page_owner_sort') were
built.
