Fix nacl_build.mk build system.

This build system which is used by several projects in the
examples folder looks like it hasn't worked at all for a
long time.  This change makes the build system work but
many of the examples that use it don't compile against the
latest PPAPI headers.

BUG=None
TEST=run 'make' for each example
