[oe] Announcing meta-musl OE/Yocto layer supporting musl C library

[Khem Raj]

Hello All

musl <http://www.musl-libc.org/> is a newer implementation licensed
under MIT licence
A layer to support musl to supply your system C library as an
alternative to uclibc and eglibc/glibc  is now available at

https://github.com/kraj/meta-musl

README describes way to get going with it.

Few things to note

* Supports gcc 4.9 in OE not 4.8
* Current musl recipe is 1.1.4 based
* You need latest master of OE-Core
(106305227003761c3fc562c21bb859a5256f2b36) or          newer and
bitbake
* Its only able to build core-image-minimal
* core-image-minimal boots on qemuarm, qemuppc, qemumips, qemux86, qemux86-64

I will send a request to add it to layerindex soon and then you should
be able to find it using
layerindex.opernembedded.org as well

If you try it out on your hardware and/or have feedback I am
interested. Fork it from github, file bugs
send patches ....

Happy hacking
