When gcc compiles the clone system call it does not bind the result register 
$v0 correctly.

I believe this patch is not required anymore.

Changes that have fixed the issue in the meantime are r21 [1] and r34 [2].

[1] r21, https://code.google.com/p/linux-syscall-support/source/detail?r=21
[2] r34, https://code.google.com/p/linux-syscall-support/source/detail?r=34
