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:

With the move to 3.2 from 3.0 in oe-core, the 3.0 no longer exists.
Prefer 3.2 instead.

-dev packages require pkgconfig, but it pulls in glib->dbus->shadow
which breaks with tiny's minimal libc.
-dev packages are not currently supported on poky-tiny.

Rather than conditionally drop eglibc-utils based on wchar support, set
USE_NLS="no" in the distro config to avoid pulling in gettext.
Also addresses some confusion over the "All rights reserved." statement by
explicitly referencing the MIT license.

Poky-tiny is intended for building very small OS images. The distro
definition sets the providers for the kernel and the runtime services.
It also reduces the eglibc component list and other DISTRO_FEATURE
elements.
