trouble building glibc-2.3.2/gcc-3.4.0/sparc64 with cvs binutils

[Dan Kegel <dank at kegel dot com>]

Sigh.  I've been trying to build
binutils-2.15.90.0.3 / gcc-3.4.0 / glibc-2.3.2
for all supported architectures (as a cross from i686-linux),
and sparc64 is just giving me headaches.  (To be fair,
m68k and powerpc64 also had trouble, but not quite as much.)

The latest error, which persists even with binutils straight from cvs, is

.../sparc64-unknown-linux-gnu/gcc-3.4.0-glibc-2.3.2/build-glibc/libc.a(dl-reloc.o)(.text+0x4b4):
In function `elf_machine_load_address.3':
: undefined reference to `_DYNAMIC'
collect2: ld returned 1 exit status
make[2]: *** [.../sparc64-unknown-linux-gnu/gcc-3.4.0-glibc-2.3.2/build-glibc/elf/sln] Error 1

That _DYNAMIC symbol is defined in glibc's link.h along with this comment:

/* This symbol refers to the "dynamic structure" in the `.dynamic' section
   of whatever module refers to `_DYNAMIC'.  So, to find its own
   `struct r_debug', a program could do:
     for (dyn = _DYNAMIC; dyn->d_tag != DT_NULL; ++dyn)
       if (dyn->d_tag == DT_DEBUG)
         r_debug = (struct r_debug *) dyn->d_un.d_ptr;
   */
extern ElfW(Dyn) _DYNAMIC[];

So something pretty low-level seems to be amiss.

Here's how to repeat this from scratch, if you like (this
uses binutils-2.15.90.0.3 with the patch mentioned at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15247#c10,
and gives the same results as cvs binutils; it builds
an entired gcc/glibc toolchain from virgin sources with
minimal patches):

wget http://kegel.com/crosstool/crosstool-0.28-rc11.tar.gz
tar -xzvf crosstool-0.28-rc11.tar.gz
cd crosstool-0.28-rc11
sudo mkdir -p /opt/crosstool
sudo chown $USER /opt/crosstool
sh demo-sparc64.sh

Here's a log showing the exact command that fails, rerun with -v:
