It's easier to have as much as possible stuff in the same place to
ease backup/restore, and make things easier to follow.
Move the host companion libraries install dir as a sub-dir of the
build-tools install dir (but not directly in it, it would break
for canadian or cross-native).

In canadian-cross, we need the companion libraries running on the
build machine, to be able to build the two core gcc.

Move the actual complibs codes to backend functions that builds the
required combo of build/host/target as requested by a frontend.
This split is currently a no-op, but is required for the upcoming
canadian-cross rework, where we'll be needing to build the complibs
twice, one for build/build, and one for build/host.
This applies to the six companion libraries:
- GMP
- MPFR
- PPL
- Cloog/PPL
- MPC
- libelf

Managing the shared version of the companion libraries
has become cumbersome.
Also, it will one day be possible to use the companion
libraries from the host distribution, and then we will
be able to easily use either shared or static libs.
As a side note, while working on the canadian-rework
series, it has become quite more complex to properly
handle shared companion libraries, as they need to be
built both for the build and gost systems. That's not
easy to handle. At all.

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.]
