   dunno, actually only a few PPC/Linux people are using snapshots right now (it
   is needed to build the egcs mainline). I get this FAIL since early January,
   981227 is the last snapshot I have without this problem. What can I do to help
   to track down this problem?

Whoops, I was confused.  I confused that test with others.  That test
was only added in January 3, so it most likely never worked on PowerPC
GNU/Linux.

That test uses a special linker script,
    ld/testsuite/ld-shared/elf-offset.ld
That linker script is probably missing something that is in the
default PowerPC ELF linker script, ld/scripttempl/elfppc.sc, which is
causing the problem.  (You can see the default linker script in a
slightly more readable form by running ld --verbose).

   maybe glibc-2.1/glibc-2.1.1pre1 enforce this? Do people on other glibc-2.1
   platforms see this failure too? Or is it PPC only?

Actually, there should be PHDR and INTERP entries also; the dynamic
linker is probably complaining about the lack of a PHDR entry.
