missing linker symbols w/ binutils-2.17

[jbbachky@aim.com]

Nick,
Thank you for making the time to investigate my problem I have rebuilt 
with the 12/06 snapshot of binutils and do not see any difference - the 
problem is still there. So I will work on creating a subset of my code 
to demonstrate the problem. Assuming I get there... how should I 
send/submit it? Attached tarball?

Thanks and TIA, John.

Can you provide a way to reproduce this problem ?

I tried to reproduce it using the script you supplied, but the symbol 
appeared in the symbol table:

  % cp hello.o lexthread.o
  % cp hello.o lexunix.o
  % arm-ld hello.o -T johns_script.t
   warning: cannot find entry symbol _start; defaulting to 
0000000000008000
  % nm a.out
  00000000005a0054 T lexunix_prefetch1_end
  00000000005a0054 A lexunix_prefetch1_start
  00000000005a0054 T lexunix_prefetch2_end
  00000000005a0054 T lexunix_prefetch2_start
  00000000005a0054 T lexunix_prefetch_end
  00000000005a0054 A lexunix_prefetch_start
  00000000005a0054 t my_variable
  00000000005a0078 t my_variable
  00000000005a009c t my_variable

This was using the current binutils mainline sources, rather than the 
2.17 release sources, so it is possible that there was a bug that has 
now been fixed.

Cheers
  Nick
