Subject: [PATCH 0/1] fs: Support compiling out the pivot_root syscall

This patch will allow for the pivot_root syscall to be made
optional. Based on feedback, this patch uses an ifdef in the
source rather than conditional compilation in the Makefile.

The pivot_root syscall is not needed on systems that do not use
any intermediate filesystem. Allowing for pivot_root to be
ommitted from the kernel will aid in the tinification efforts.
