poky-tiny: Separate the libc features required for meta-toolchain
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:
