[Buildroot] [RFCv1 06/11] toolchain-buildroot: convert to the package infrastructure

[Thomas Petazzoni]

This commit converts the toolchain-buildroot logic to the package
infrastructure. The package is fairly simple as it only defines
BUILDROOT_LIBC, and depends on host-gcc-final to get the overall
internal toolchain build logic started.
