Fails to build with clang trunk

[GoogleCodeExporter]

Clang will parse inline assembly, so the vp8_asm_enc_offsets trick doesn't work.

One option is to turn it into valid assembly. The other is to disable the 
integrated assembler (with a check for -fno-integrated-as being supported)

This is related to the issue with ticket 708 it seems. The patch provided seems 
to work as a workaround and I can now build libvpx.

We are in the process of removing asm_offsets.
