There is bug in the eglibc configure scripts that prevent a
x86-64 from configuring correctly and finding the smaller
library fucntions.

Currently poky-tiny images will boot and run /bin/sh, which results in
error messages to the console about being unable to open the tty and job
control being disabled.
The shell must be session leader to open the tty, and the tty must not
be /dev/console (it should be a vt or a physical tty like ttyS0), the
tty is required for job control (handling signals, etc.).
The goals of poky-tiny are to be an initial starting point from which to
build a distribution that does what you want, and NOTHING more.
This patch results in a system that boots with the virtual filesystems
mounted, the local network interface up, and a shell with job control
running, and a hook (/etc/rc.local) for easy customization. Nothing
else.
Enabling the basic busybox init, including the ability to give the
controlling console to commands starting with a dash in inittab results
in a 5664 byte delta (compared with 2560 bytes for enabling setsid and
cttyhack). Note that the help in busybox suggests the cttyhack may be
more reliable than the init support for handing over the controlling
terminal.
So the difference between using a standard init and just enabling the
two options is about 3k, but enabling setsid and cttyhack may enable
others to things besides what I am looking to do. Enabling init in both
DISTRO_FEATURES and busybox is fairly trivial to do, so I think it's
better to leave that as something to add if needed, rather than
something to remove, as that is more consistent with the goals of
poky-tiny.
Thanks to Tim Bird for his suggestion to include support for rc.local by
default.

This fixes bug [YOCTO #2295]
eglibc needs libc-posix-regexp-glibc & libc-libm-big enabled in its
configuration to avoid following eglibc build issue. Thanks to
Nitin for identifying the required features.

The libc features added to support building meta-toolchain add 461KB to the C
libraries. 320KB directly to libc (a 32% increase in size). If not building
meta-toolchain, the user should be able to easily configure these out.
Create a new variable to capture these dependencies,
DISTRO_FEATURES_LIBC_TOOLCHAIN, keeping them separate from the core tiny
requirements. Make it clear how to disable these if meta-toolchain is not
needed.
This patch has been tested by running the following for the qemux86 machine with
DISTRO=poky-tiny:
$ bitbake -c cleansstate eglibc
$ bitbake meta-toolchain
$ bitbake core-image-minimal
The libc comparisons were made from core-image-minimal ext2 filesystems build
before and after the applicaiton of this patch and Nitin's previous poky-tiny
libc features patch in support of meta-toolchain:

-dev packages require pkgconfig, but it pulls in glib->dbus->shadow
which breaks with tiny's minimal libc.
