Update tinyscheme from version 1.33 to 1.35, to pick up bugfixes:

     Version 1.35
          Todd Showalter discovered that the number of free cells reported
          after GC was incorrect, which could also cause unnecessary allocations.

     Version 1.34
          Long missing version. Lots of bugfixes have accumulated in my email, so
          I had to start using them. In this version, Keenan Pepper has submitted
          a bugfix for the string comparison library procedure, Wouter Boeke
          modified some code that was casting to the wrong type and crashed on
          some machines, "SheppardCo" submitted a replacement \ 
"modulo" code and
          Scott Fenton submitted lots of corrections that shut up some compiler
          warnings. Brian Maher submitted instructions on how to build on OS-X.
          I have to dig deeper into my mailbox and find earlier emails, too.

Additional pkgsrc fix: use BSD_INSTALL_LIB to install libraries.
