Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain
The IA32 Sourcery CodeBench toolchain has a relatively special structure, with the following multilib variants: * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to the main sysroot, with the libraries in the lib/ directory. * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative to the main sysroot, with the libraries in the lib64/ directory. * Intel Atom 32 bits, the multilib variant is in atom/ relative to the main sysroot, with the libraries in the lib/ directory. * Intel Core 2 64 bits, the multilib variant is in core2/ relative to the main sysroot, with the libraries in lib64/ directory. So the first two variants are in the same sysroot, only the name of the directory for the libraries is different. Therefore, we introduce a new ARCH_LIB_DIR variable, which contains either 'lib' or 'lib64'. This variable is defined according to the location of the libc.a file for the selected multilib variant, and is then used when copying the libraries to the target and to the staging directory. In addition to this, we no longer use the -print-multi-directory to get the ARCH_SUBDIR, since in the case of the 64 bits variants of this toolchain, it returns just '64' and not a real path. Instead, we simply compute the difference between the arch-specific sysroot and the main sysroot. We also take that opportunity to expand the documentation on the meaning of the different variables.
