[git commit avr32-prctl-fix] avr32: add varargs handling of prctl syscall

[Hans-Christian Egtvedt]

commit: http://git.uclibc.org/uClibc/commit/?id=2b69e9906e5087a796b3a15e9aabcd102c705b19
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/avr32-prctl-fix

prctl is defined to use varargs in the header file, hence it needs varargs
specific handling in the source. This patch properly handles the variodic
argument before the syscall is passed to the kernel for the AVR32 architecture.
