For example a microcontroller do not need to have any kind of standard
C-Library files or its header files.
So it is not possible to build e.g. zlib or libiberty for this

The original failing process was:
../../env/src/configure --prefix=${HOME}/local --with-mpc=${HOME}/local
--with-mpfr=${HOME}/local --with-gmp=${HOME}/local --with-ppl

Since I did not need to have libc I also did not need to have libstdc++-v3,
too.
Also I did not need to have libgomp, libmudflap, libffi, libssp, libquadmath,

Exactly this is the current problem, there is neither a working switch like
--disable-target-zlib nor a working --disable-target-libiberty.

If you can't imagine how to get a usable C++ compiler without libstdc++-v3 (and
libc), please stop wasting your time in thinking about it.
Here is no C++ problem at al

The commit helps suppress building of target-libiberty.
But there is still a try to build target-zlib.
Isn't it possible to add a manual switch to prevent building of
