libelf is used by gcc to build the lto-plugin used
by binutils' gold to perform LTO.
This requires that files in libelf be compiled with
-fPIC to generate a proper .so.

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.
I ran into some minor difficulties looking through the build log for a
particular file: I wasn't interested in seeing it unpacked, but only
when it is built or installed. Adding these two levels allows me to
differentiate between those cases.
[Yann E. MORIN: Those are blind log levels, and are used only to search
in the build-log afterward.]
