SPARC build failed

[syoyo]

SPARC build of iv/lv5 fails with libgc related issue.

http://qiita.com/syoyo/items/0068f514f606a6b1a91e

It looks like some file(s) are missing in CMakeList.txt when targeting SPARC architecture.

At least, with the following patch, I could get success to build libgc.

$ make

Cool! I've added the support code to CMakeLists.txt. Coud you try it?
Since this CMakeLists.txt is basically derived from the original source of BoehmGC, once this issue is fixed, we can contribute BoehmGC repository to fix CMake build on SPARC :)

This works on our SPARC, finally!
