Fixing examples/scala/Makefile

Fixing the problem that was caused by this PR: #189

[boyland]

Not working yet:

$ make
make: *** No rule to make target `nested-cycles.scala', needed by `obj/DYNAMIC/nested-cycles.class'.  Stop.

It builds fine locally. I did a fresh clone. Please make sure to run git clean -f in the examples/scala folder

examples/scala Makefile default runs as part of the build sanity check, so everything should be fixed now

My previous problem eas because I hadn't made install at the top. A new clone needs that of course.
Now I get:

boyland@UWM022518 scala % make
../../bin/aps2scala -p ..:../../base -G nested-cycles
../../bin/aps2scala -p ..:../../base -G simple
scalac -cp .:obj/DYNAMIC:../../lib/aps-library.jar -d obj/DYNAMIC simple.scala
simple.scala:2: error: not found: object basic_implicit
import basic_implicit._;
       ^
simple.scala:8: error: not found: type C_TYPE

This appears to be because base/scala doesn't build aps-library.jar

Oh, I need to make install too. Much better now.
