Add a mechanism to construct a full cross-compiler environment using the "crosstool-ng" cross-compiler building utility. This is implemented in the new "common.crosstool" include, and augments the "dockcross/base" base image. Update Makefile to consolidate Dockerfile generation, notably the "sed"-based inclusion directives. Finally, employ all of this to generate a "linux-mips" 32-bit hard-float MIPS cross-compiler Dockcross image.
