The autofs configure script verifies on the build system if /proc is
provided by a Linux system. This might fail if /proc is not mounted,
but does ont mean that procfs will not be available in the target.
Therefore, this commit adds a patch improving the AF_LINUX_PROCFS
autoconf macro to allow passing an autoconf cache variable. autofs.mk
then uses that to force the fact that /proc will be available on the
target.

Autofs 5.1.2 switched to clock_gettime() unconditionally but didn't
check for the need of librt (glibc < 2.17) for it. Fixes:

Since we don't have such packages in buildroot it can pick up the distro
config scripts and pollute the include path.

The autofs configure script does a number of weird things.
First, instead of using the default search path for AC_CHECK_PROGS(),
it overrides it its own search path, ignoring the PATH environment
variable. Due to this, autofs fails to find flex even though flex is
available in the PATH. Fortunately, the authors provided a --with-path
configure option which allows to override this search path.
In addition, the configure script is checking on the build machine
that a number of programs are available, while those programs are in
fact only needed on the target. The one causing build issues is
modprobe, because it may not necessarily be installed on build
machines, so we explicitly tell autofs that modprobe is located in
/sbin/modprobe. It might be necessary to provide additional values for
other programs, as we discover other problems.

Tested on i.MX6 using NFS mounts only. Not tested with DAS mounts as
of this commit.
[Thomas:
- remove the "# rpcbind" comments on the thread and mmu dependencies,
since we don't select rpcbind. The thread and mmu dependencies are
still needed though, since autofs uses pthread_*() functions and
fork().
- Remove "Requires a toolchain with native RPC." in the Config.in
help text and instead add a proper Config.in comment about the
thread and RPC dependency.
- Add patch to fix building with uClibc, taken from OpenEmbedded.]
