When cross-compiling LLVM itself the configure/make scripts get confused when creating the needed build host tools. For example, building and configuring like: CC_FOR_BUILD='i686-pc-linux-gnu-gcc' CXX_FOR_BUILD='i686-pc-linux-gnu-g++' CXX='i686-mingw32-g++' CC='i686-mingw32-gcc' LD='i686-mingw32-ld' /scratch /meadori/llvm-trunk/src/trunk/configure --host=i686-mingw32 CC_FOR_BUILD='i686-pc-linux-gnu-gcc' CXX_FOR_BUILD='i686-pc-linux-gnu-g++' CXX='i686-mingw32-g++' CC='i686-mingw32-gcc' LD='i686-mingw32-ld' make causes the following build break: checking whether the C compiler works... configure: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details. The 'config.log' shows that i686-mingw32-gcc is being used to create executables for the build host. This patch fixes the problem by propogating the names of the build host tools via BUILD_* when configuring/making BuildTools. Original patch by Ekaterina Sanina. llvm-svn: 204760
