[Buildroot] [PATCHv2 00/10] musl support, internal and external backends

[Thomas Petazzoni]

Hello,

This patch series does two things:

 * Adds the musl support in the internal toolchain backend.

 * Adds a set of pre-built musl toolchains to the external toolchain
   backend.

Compared to v1:

 * The issue of the symbolic link for the dynamic linker noticed by
   Peter is fixed. In fact, the musl Makefile can create this symbolic
   link perfectly fine if we are in the good conditions.

 * A patch for musl support in gcc 4.9.0 has been added.

 * The patch for musl external toolchains has been added, and after
   the suggestion from Arnout, a single Kconfig option is now used
   instead of one per architecture.

I've built and boot tested under Qemu ARM/musl/gcc4.8 and
i386/musl/gcc4.9.

Thanks,

Thomas
