[configure/make] Propagate names of build host tools when making BuildTools
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.
