re: build error

stringify will not automatically build when cross compiling.
This is because it needs to be the the host arch, not the target arch.
[As discussed here](https://github.com/PixarAnimationStudios/OpenSubdiv/tree/6b22e10875de77786d25c32ae23089f6558e994b#ios)

Sorry if you already knew this.
