tinyscheme: Tweaks to allow building libraries

Causes the libtinyscheme.a and libtinyscheme.so to also be built,
which builds successfully on mips_24kc targets at least. This patch
causes them to be built in build_dir but not actually included in the
ipkg.

 	TinyScheme is a lightweight Scheme interpreter that implements as large a
 	subset of R5RS as was possible without getting very large and complicated.
