ARC: Support building of multi-lib Glibc toolchain From GCC's standpoint ARC's multilib items are defined by "mcpu" values which we have quite a few and for all of them might be built optimized cross-toolchain. From Glibc's standpoint multilib is just multi-ABI [1] and so very limited versions are supposed to co-exist (e.g. arc700 & archs). Here we force Glibc to install libraries in GCC's multilib folder to create a universal cross-toolchain that has libs optimized for multiple CPU types. But note we only need to mess with installation paths in case of real multilib, otherwise we keep default "lib/" paths so that GCC finds default (the one and only) libs where it expects them to be. Also here we add a sample which allows to build universal Glibc Linux toolchain for ARC.
