Stephen Smalley 5a8d8c499b libselinux: only mount /proc if necessary
Commit 9df4988846 ("libselinux: Mount procfs before checking
/proc/filesystems") changed selinuxfs_exists() to always try
mounting /proc before reading /proc/filesystems.  However, this is
unnecessary if /proc is already mounted and can produce avc denials
if the process is not allowed to perform the mount.  Check first
to see if /proc is already present and only try the mount if it is not.

Build dependencies on Fedora:
yum install audit-libs-devel bison bzip2-devel dbus-devel dbus-glib-devel flex flex-devel flex-static glib2-devel libcap-devel libcap-ng-devel pam-devel pcre-devel python-devel setools-devel swig ustr-devel

To build and install everything under a private directory, run:
make DESTDIR=~/obj install install-pywrap

To install as the default system libraries and binaries
(overwriting any previously installed ones - dangerous!),
on x86_64, run:
make LIBDIR=/usr/lib64 SHLIBDIR=/lib64 install install-pywrap relabel
or on x86 (32-bit), run:
make install install-pywrap relabel

This may render your system unusable if the upstream SELinux userspace
lacks library functions or other dependencies relied upon by your
distribution.  If it breaks, you get to keep both pieces.
