| 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. |
