'Hello world' from m68hc11!
I finally managed to build everything using an "ancient" version of Ubuntu: 5.10 "Breezy Badger"
with a native 4.0 gcc compiler and 2.16.1 binutils.
Although binutils 2.15 did not compile (patch or not), 2.16.1 did compile. And so did gcc-3.3.6
(no patch). The only prerequisites were apt-get install build-essential.
Thank you everyone for your help.

Subject: building cross-compiler for m68hc11/m68hc12
I am trying to build gcc-4.3.2 as a cross compiler for the Motorola m68hc11 target on a standard, clean installation of Ubuntu 11.10 32-bit. I also want to build binutils (2.19) so I included the binutils-2.19 directory (without stripping the version from the name) inside the gcc-4.3.2 directory.
The versions have been chosen arbitrarily in the thought of minimizing the port's potential compatibility issues with newer versions while still using rather contemporary iterations of both gcc and binutils.
I have downloaded the source code for the MPFR, MPC and GMP libs from gcc/gnu/org/pub/gcc/infrastructure and included it in the gcc-4.3.2 directory in corresponding directories (stripping the version number) so they are built together with GCC and binutils.
My srcdir is /home/mihai/licenta/gcc-4.3.2 and my objdir is /home/mihai/licenta/hcs12x. Everything has r/w/x rights. The configure command I have run is:
cd hcs12x
../gcc-4.3.2/configure --prefix=/home/mihai/licenta --enable-languages=c --target=m68hc11
I am not sure if the configure parameters are enough, nor am I sure whether the name for the target is m68hc11 or some other variation: m68hc11-elf, m68hc11-linux or m68hc1x. The config output says: "checking target system type ... m68hc11-unknown-none" so it is not clear to me whether gcc recognizes the target.
Building the compiler with make fails with the infamous error:
"configure: error: cannot compute suffix of object files: cannot compile"
while in directory hcs12x/m68hc11/libgcc
Here is a fragment of the respective config.log:
configure:2376: /home/mihai/licenta/hcs12x/./gcc/xgcc -B/home/mihai/licenta/hcs12x/./gcc/ -B/home/mihai/licenta/m68hc11/bin/ -B/home/mihai/licenta/m68hc11/lib/ -isystem /home/mihai/licenta/m68hc11/include -isystem /home/mihai/licenta/m68hc11/sys-include -V </dev/null >&5

Any help is greatly appreciated, both with the issue at hand (permission denied) as well as with potential omissions / mistakes I've surely made.
