Make will only ever try to build the first target in the makefile,
unless you give it some targets to build on the command line. Since "a"
is the first target here, by default that's all make will build.
If you run "make a b", it will build both. Most people use an "all:"
target in their makefiles and put that first, then list all the
top-level targets they want built by default as prerequisites:
all: a b
a b: c ; touch $@
