 I just checked this with the latest nightly source bz2 file and it's still
 a problem. I am compiling on a Ubuntu Desktop 12. I'm compiling for
 Synology NAS embedded systems that have multiple CPU architectures, using
 their various GCC toolchains available here:
 [http://sourceforge.net/projects/dsgpl/files/DSM%204.1%20Tool%20Chains/]

 Cross-compiling using their Intel toolchain is fine, so is cross-compiling
 for PowerPC-SPE (QorIQ). Only cross-compiling for ARM exhibits this
 problem (native compile is actually ok), and the issue can be circumvented
 by disabling the zmbv encoder at the configure stage.

 Here is the error output:

 Here's how I'm building:
