Thanks! I applied the patch, and rebuilt everything. GLIBC now builds,
*seemingly*, ok; but when I try to compile a full cross-gcc-3.2.3,
directing it to use the newly compiled target glibc, I get the
following error:

/opt/xdvl/toolchain/bin2.13.2-gcc3.2.3-glibc2.3.2/bin/arm-linux-ld:/opt/xdvl/toolchain/bin2.13.2-gcc3.2.3-glibc2.3.2/arm-linux/lib/libc.so: file format not recognized; treating as linker script

And obviously the contents of my new "libc.so" are buggy:

/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
*** BUG in libc/scripts/output-format.sed *** elf32-bigarm,elf32-littlearm
GROUP ( /opt/xdvl/arm-linux-glibc/2.3.2/lib/libc.so.6 /opt/xdvl/arm-linux-glibc/2.3.2/lib/libc_nonshared.a )

Searching the build-output logs produced when building GLIBC, for
"output-format.sed" I found the following relevant stuff:

arm-linux-gcc  -shared  -Wl,-dynamic-linker=/opt/xdvl/arm-linux-glibc/2.3.2/lib/ld-linux.so.2 -Wl,-z,combreloc \

mv -f /opt/xdvl/arm-linux-glibc/2.3.2/lib/libc.so.new /opt/xdvl/arm-linux-glibc/2.3.2/lib/libc.so

The contents of "format.lds" (found in the glibc-build directory) are:

*** BUG in libc/scripts/output-format.sed *** elf32-bigarm,elf32-littlearm

Could this be due to a buggy sed?

sed --version
  
  GNU sed version 3.02

ldd `which sed`

  libc.so.6 => /lib/libc.so.6 (0x2aac8000)
  /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaab000)

ls -l /lib/libc.so.6

  /lib/libc.so.6 -> libc-2.1.3.so*

Thanks again

Recaping for those tuned-in lately:

I was trying to cross-compile GLIB-2.3.2 tagering arm-linux (and
hosted on a i386 linux machine). I used a recently built
cross-toolchain targeting arm-linux, comprising of binutils 2.13.2 and
a minimal GCC-3.2.3. Initially the assembler chocked at some point. I
applied the patch mentioned in the quoted text above and...
