Building a cross compiler from i686 (the platform of my linux) to s390
I get the following when the bootstrap process is configuring in
s390-ibm-linux/libgcc:
configure:3268: /usr/ports/gcc390/build460/./gcc/xgcc
-B/usr/ports/gcc390/build460/./gcc/
-B/usr/ports/gcc390/inst/s390-ibm-linux/bin/
-B/usr/ports/gcc390/inst/s390-ibm-linux/lib/ -isystem
/usr/ports/gcc390/inst/s390-ibm-linux/include -isystem
/usr/ports/gcc390/inst/s390-ibm-linux/sys-include -c -g -O2
conftest.c >&5
exec: 89: -m31: not found
I configured with:
/usr/src/gcc-4.6.0/configure --prefix=/usr/ports/gcc390/inst
--target=s390-ibm-linux --host=i686-pc-linux-gnu
However, once the directory is in the path, the bootstrap compiler
does work as far as doing
u@ubuntu:~/src/testing$ /usr/ports/gcc390/build460/gcc/xgcc -S x.c
an even
u@ubuntu:~/src/testing$ /usr/ports/gcc390/build460/gcc/xgcc -m31 -S x.c
u@ubuntu:~/src/testing$ /usr/ports/gcc390/build460/gcc/xgcc -m64 -S x.c
and what is more, the two invocations generate the expected assembler
for return 0x1000000.
But the error is reproducible:
u@ubuntu:~/src/testing$ /usr/ports/gcc390/build460/gcc/xgcc x.c
exec: 89: -m31: not found
there is no 89 or c89 in the gcc directory.

This looks like you don't have a cross-assembler. You need to make and
install the GNU binutils first with the same --host, --target, and
--prefix options. Then start again with gcc in a brand new empty build
directory.

Thanks, Ian. That brought me further, but still no cigar. Does the
following ring a bell?

So I looked for string.h in the source:
u@ubuntu:/usr/src/gcc-4.6.0$ find . -name 'string.h'
./libssp/ssp/string.h
./fixincludes/tests/base/string.h
./libstdc++-v3/include/c_compatibility/string.h

Since you are trying to build a cross-compiler to a GNU/Linux system,
you may want to look at http://crosstool.org/ .

Thanks Ian.
http://wiki.osdev.org/GCC_Cross-Compiler suggested
--enable-languages=c,c++ --without-headers --disable-nls but that made
no difference. So I gave the target a symbolic link to /usr/include,
and then it failed in linking because of missing object decks. Seems
like the process is building something I didn't ask for, or at least
do not want.
What I am after is in fact a cross compiler to s390 os/360 object
(well, the variety that supports long ESD names--and not the old MVS
attempt.) As I already have a cross assembler, I guess I should
simply take the intermediary xgcc and run.
I did come across crosstool in my googling, as well as a number of
sites bemoaning the quality of documentation of gnu cross compiling.

Information on [modern] cross compiling is horrible. If I recall,
crosstools is terribly out of date (or at least the website). Have you
looked at crosstoolng (http://freshmeat.net/projects/crosstool-ng/)?
An up to date book, including cross-compilation, would be very
welcomed (hint to Ian and Jonathon).
