[PATCH] libelf to use host compiler

Hi,

It appears, that the configure scripts of libelf versions 0.8.13 and 0.8.12 do not honour the --host option. The compiler must be given as an environment variable or the process will use the command "gcc" as the compiler.

It seems that this is already done in the function do_libelf_target in scripts/build/companion_libs/libelf.sh, but not in function do_libelf.

Here is a patch for using the CT_HOST compiler when compiling libelf:
