+    Allow target autodetection to work when cross-compiling.
+    
+    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.
