Allow CHOST to override the gcc -dumpmachine output. This allows to use the target autodetection code when cross compiling by setting the CHOST variable. On Gentoo, we would like to support easy cross-compilation, and for libvpx this would basically mean copying the code in build/make/configure.sh to setup the right --target option. It seems a lot easier to let it guess by itself. Another option I considered was using CROSS-gcc instead but this would not work for our multilib setups: They use gcc -m32 to build 32bits binaries and gcc -m32 -dumpmachine will output the 64bits version, which would then make libvpx wrongly believe it is building for a 64bits architecture.
