[gentoo-musl] musl/libc++ (clang, no gcc) bootstrapped stage4

[Jens Staal]

Dear all,

Inspired by the list of alternative libraries from the musl project [1]
and the "native clang" GSOC project [2], I have made a bootstrapped
stage4 variant that some people might wan to play with.

I have eliminated the dependency on gcc (all stdlibc++-dependencies
compiled out, gcc uninstalled, alternative crtbegin/end from ELLCC
included)

My experimental stage4 can be found here:
(any good ways to share stage4 builds?)

The current variant have a few alterations from the normal musl stage3:

1. gcc --> clang:4 (libc++, c++abi, ellcc crt)
(note: had to move __dso_handle from crt1.c to crtbegin.c for it to
work)
2. readline --> libedit : a surprisingly simple replacement
3. openssl --> libressl
4. nano --> vim (personal preference)

+ some useful stuff (gentoolkit,eix,...)

Several TODOs (most importantly an up-to-date llvmlinux overlay to have
a self-hosting system)
Another thing that would be nice is a "fake" gcc-config that can point
to the clang installation (some packages like busybox rely on gcc-config
to find the complier)

Hopefully some of you will enjoy playing with it. I am going to abuse
the system further to see how much alternative implementations I can
implement in the system.
