[Libclc-dev] buliding for arm or x86_64

I am trying to build libclc for arm or x86_64 by slightly modifying the
configure file(adding x86_64 and arm as available target).

I just bumped into some problems: It can't build all the functions

x86_64: cross.cl dot.cl fmax.cl, fmin.cl ... etc are ok. When it comes to
hypot.cl, it fails.

the following are the error msg.

It says it does not mangle correctly, but it does not show up at r600 and

Does anyone know how to build libclc for arm or x86_64 correctly?

Thanks your kindly help very much.
