Yeah, I managed to get access to a solaris-2.8 machine, even though I 
wasn't able to bootstrap with Solaris as/ld (see below), I was able to 
reproduce the failure. Re-checking on x86-linux-gnu revealed that it even 
doesn't fix the problem there, so I must have mixed something up yesterday. 
Frankly, I'm a bit at a loss here, cause I've tried several strategies 
yesterday and they either didn't fix the testcase or caused some of the 
weak tests to fail. Especially I tried to use the TREE_USED flag of the 
WEAK_DECLS TREE_LIST to mark when a weak already had been assembled, but it 
didn't work out :-(. I seem to misunderstand something about how the tree 
structures are handled.


The bootstrap failure with solaris-2.8 as/ld and configured with:

          --enable-shared \
          --enable-threads \
          --with-system-zlib \
          --with-libiconv-prefix=/usr/local \

This results in:

strcpy                              0x42c 
strdup                              0x694
